Thanks for the suggestions guys I have sent off inquiries to the companies mentioned.. my torch is from the 60s and it is a smaller unit, but looks identical to any Victor handle, that we used on a commercial fishing boat that I worked on during summer school breaks. The markings on the handle show TYPE 100 and the serial #62524 as well as Victor Equip Co. SF Calif. The marking on the cutting tip shows Victor 550-100. The markings on my cutting tip which I was advised not to use any longer shows. Victor 500/ 1-5-101/ Victor 1 My restoration interest is in its use as well as nostalgia reasons which sometimes can be expensive. I need to learn how to post photos but didnt find a suggestion of how to do so on a recent search??? thanks again
