Dont know if any of you guy's can remember the Ergo kit using a bottle of oxygen and a small bottle of MAL gas. These are ancient , I bought mine second hand over 30 years ago.I cannot get the gas anymore and not even sure if I can get the oxy bottle re-filled . I was wondering if it's possible to use another type of gas .ie propane etc, of course that's if I can still get the big bottle re-filled. I have a picture of the setup some where ,I'll have to dig it out. If not it maybe destined for the tip, shame really as it was a nice little portable brazing kit.
