Too many pics lumped in together to easily identify each one for you. But thing at the top is a Coventry die head for cutting threads on repetition production work but handy for home use for making threads.
Next is a hand held knurling tool, very handy for making grips and footpegs and things with a knurled pattern on them.
The a pair of brass oilers for the lathes headstock bearings. Very nice old ones they are too.
Next is a Myford 4 way toolpost with ratchet mechanism. I would buy that from you if shipping to Australia was not so extrotionate and slow right now.
Next is two unrelated items. Left is a hand tool steady rest used for wood turning, steel graving or to support the handheld knurling tool above. Right is Myford angle plate for use on the faceplate (like a chuck only big slots in it).
Next is a live centre and a drill chuck. Now here is why you should not be selling all this stuff just yet. You will need these for making motorcycle spacers that need any kind of hole drilled up the middle of them or for axles and engine bolts etc that are long and thin and need supporting while being machined.
Then there is some stuff I cant identify from the pics.
Starting from the bottom, first is a box of centre drills you will definitely need is you drill a hole up the middle of a spacer.
Next up is a Myford "clog" type of toolpost clamp in black, with a bunch of junk above it.
Random spanners then a Morse taper adaptor that you will most likely need to hold small chuck or centre in the tailstock.
You should put it all for sale individually in the classified ads on this forum, at the right of the page. None of it is worth very much. But it might find a good home with a model engineer here if you are open to offers.
I would buy that Sparey dividing head and gears just as a curiosity but again shipping is prohibitive. There might be some other old Luddite closer to you who might be interested in it.
