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**
