Dillon, Henrob, and Cobra are all the same torch. Cobra Torch in Michigan is the parent company now. www.cobratorches.com  List of dealers are on the site. Canadian dealer in Leamington (I didn't know about him until I looked this up.) I've been buying parts etc. from J&S Enterprises in SC, I'll have to check out the Leamington dealer myself, he's not that far from me. He may have a line on a used set, might be worth contacting him. Bought mine new in the early 90's and it fills a certain void, won't do everything,but certainly has it's place.
