I find this model interesting because I don't ever remember seeing one even in my 20/30 year old Harris catalogs. It appears to be a light weight model. i used an old Harris torch handle and tips designed for acetylene but used with propane in Ukraine as a substitute for the horrible Russian thing we started out with. It worked kinda okay but was not ideal. Harris is a high quality manufacturer and they are the most expensive brand on the market. However there are several cautions. The cost to buy the proper mixer and elbow and various tips to work with propane may make this deal unattractive even if it is given to you. Remember Harris accessories are going to be more expensive than other brands. I think Granger's sell Harris equipment.

Another caution is that if it is as old as I think it is, the diaphragm on the acetylene regulator probably is shot and needs to be replaced. I wouldn't want to take a chance that it might leak and go boom! If you get it serviced you can have them put in the seals that work with propane. Once you start to add up the corrections and bother you might want to start with something else.
