Potentually, one of the best bargins (in aircraft torches) on ebay right now. It is very similar to the Victor J-28 (Victor "J" series tips can even be used). Uniweld has been around a long time - decent stuff (one of my backup torches is the model 71).

I know nothing about this seller, so you're on-your-own if you decide to bid.
