Vintage Smith Regulators H100, H101J. Condition used. NOT TESTED, purchased a torch outfit from a retiring auto repair shop owner, online auction. I think they still work as set was still being used by previous owner, I had to disassemble things to get it in bed of my truck by myself. I have a new torch and regulator set and don't need any more stuff sitting around here. Oxygen H100, Serial number 33121- looks all original, 200 lb. and 4000 lb..Acetelyne H101J, Serial number 48326-looks to me like output gauge is replacement, lens on tank gauge looks like it has some heat damage- see photos. 30 lb.and 400 lb.
