I have Victor torch that I bought at a flea market for a very good price. I am trying to ID it so I can repair the gas valve, will not shut off completely. The torch has what appears to be a model number of WH-2600 and a few other numbers that I can not make out because of scratches. I have looked on the Victor site but can not find the model number. Can this model number be cross referenced to another model number and if so what is the current model number?
