        So, I've done a little bit of perusing today and in an antiques shop i found an old blowlamp, or what i think is one.

        It's made of brass and marked "Vespa FJ Paris" , it appears to have an air regulating screw with a small needle on the head, and a port for filling up with fuel.

        But i was totally puzzled by why this model has no pump, it's just totally absent. Then i noticed a small well around the head of the blow lamp with blackening around it from flames, so i presume i fill this with meths and burn off the meths to get it warm enough to start the torch.

        I've read about "atmospheric ambient" style lamps which have no pump.

        I liked it the moment i saw it so i bought it, but would like to try giving it a run. I just haven't used these old style ones before i wondered if anyone knows why this has no pump mechanism and what sort of fuel/procedures i need to know to get it up and running, i have no photo at the moment but will get one later.Heres a link to a similar one. **LINK**

          Is that a small pump on the filler cap?

            Hi KWIL,

            Yeah i've now noticed that this one has a port the other side, whereas mine has just one cap with a brass wing nut.

              If it has no pump it may be intended for use with petrol. Please be careful I don't want to lose any subscribers!

                Michael,

                I dont collect blow lamps but I do collect campingstoves, 135 and counting, first of all you need to make sure the jet is clean, the adjusting screw acts like a tap to increase or decrease the flow of paraffin, inside the heat sheild is there a coil, coming and returning to the tank. Unscrew the filler cap and check to see if there is some lead blocking a small hole, this is the fusible plug which melts if the temperature is to high, this needs to be intact.

                As you have said there is a well this is where you put meths to heat the coil, using the heat paraffin is drawn up and vapourised once its nice and hot open the valve vapourised paraffin is allowed to leave and be ignited by the meths which when the meths runs out the vapourisation is kept running by the paraffin.

                  There are some single port ones on ebay.fr .

                  Alcohol / petrol type. Heat transfer is enough to create pressure. see video

                    There are some single port ones on ebay.fr . Is it possible that the pump got removed and replaced by a plain cap? You can imagine a plumber in a hurry swapping over a working pump when his main one needed repacking and then not sorting the bits out later. Or could it be prepressurised off an air line.

                    I did think about that bazyle, as the cap has a steel nut on it, but it's hexagon edges are completely smoothed over, indicating that it is atleast an old assembly, maybe someone retro fitted it for a compressor?

                    I intend to have a gander at the innards with a small torch.

                      Ha, i have heard on a youtube vid that the older ones used leaded petrol, and a stern american said "i aint gonna give ya no warning bout saftey and what nots because if you're old enough to be doin this stuff, you're old enough to care of yerself" They can be quite volatile,

                      I'll try to avoid drinking the denatured alcohol too, i'm not that desperate yet though.

                      Thanks for the warning,

                          I have a sievert blowlamp that runs of Benzoline. It works with petrol though and it doesn't have any pump or a spot where a pump could have been added. The heat of the starting meths fire is enough to build up the pressure.

                              Here is the "Vera Icona" or true image, of the lamp.

                                  I have a very small petrol primus stove. This does not have a pump. Just put hand round tank to warm it up, the little trough fills with petrol, throw a match at it, couple of minutes later boiling water for cuppa. Elf and safety would have complained but in wet weather have even lit it in the drivers footwell of the car. The flame is not very big at all. The other option is to use a fire starter jelly that comes in a small tube.. A small squirt into the trough, light it and a few moments later away you go. I also have a selection of old paraffin blow torches. These all have a trough which fill with meths. The old Tilley lamps are similar but in some cases they have a small clamp with a felt pad which is soaked in meths or paraffin and then lit to warm up the lamp assembly prior to pumping up the pressure. Always need to make sure the jet is pricked to ensure clean flow of fuel.

                                    I'v got a Sievert lamp (was my Plumber Grandfather's), it's like Rainbow's one, it will run on petrol or white spirits.

                                    To start it, after filling the tank, pour some meths in the little trough on top, close the valve, light the meths, and when the flame is near finished open the jet. This lamp is the reason I went over to a gas torch, one day I was at the garage door way when the flame blew back through a leak in the control valve spindel, I dropped the lamp on my toe, and kicked it across the back yard, I don't know if it was the trip through the air, or the sudden stop, but the flame went out. It's been repared, and it sits on the shelf.

                                      Yeah, i suspect mine is the same, thanks for the advice, i'm sure they are all nice things to look at even if you don't use them. I just like to have an alternative if nothing else is available, if i want to do any real work i just use propane gas.

                                          In the sixties we had a couple of these in the ARP hangars at Weyhill and used to do the daily brews on them. Filled with petrol and pumped up they used to roar disconcertingly when boiling the water for our brews. They frequently erupted in flames and the first time I saw it and panicked the staff sergeant said "leave it alone, it’ll burn of in a bit” – and it always did. kulou

                                            In my large collection of Camping Stoves, I have several that are petrol powered, mostly military, I test every one once I've replaced the seals and checked that the lead plug is sound and there are no leaks, i've had the odd flair up but as stated if left it will settle. I never run them inside, even paraffin powered stoves will flair up.

                                                The military petrol stove mention by Rick was basically the same cooking stove we cooked our meals on our tanks and ferrets well into the late 1970's.

                                                On exercises our cooks delighted us with their fiery early misty morning displays of petrol vapour lighting up the ground around their cooking trenches with the British army No1 burners, brave men.

                                                I still use a optimus petrol stove from the early 70's

                                                  I seem to recall a chap in here from the BAOR

                                                  If it was useable they stuck petrol in it and used it, otherwise the British Army wouldn't have had cups of tea and various hot foods after 1950

                                                  Parafin was as common as 12 year old Glenlivit back then

                                                    The Kiwis will know what I'm on at, the Thermette, the NZ army used them in North Africa, it's said that you could tell the New Zealanders had been here, a little pile of ash about 6" diameter. These things are like a vertical boiler, about 18" tall, and 6" dia. Most of them made of tin plate steel, posh ones made of copper, a hand full of little sticks, and about 5 minutes and the cupper is boiled, some people made a support to go on top where you could put a fry pan. The army also had a stove made from petrol cans (square 4 gal), under this a tray of sand, some petrol pour into the sand, and lit up, this was to cook for a platoon. I think the British army also used the petrol stove, it was known a a Benghazi burner.
