I just refinished a Husqvarna model 15 using Peter Dyson's Damscus browning chemicals (http://www.peterdyson.co.uk/). I am very happy with the resuts. I think it was around $25 including shipping to the US. You also need some copper sulfate that you can pick up at a hardware store. Take your time with the polishing of the steel. Like any finsihing work it is all in the preparation. You will spend a week rusting and carding once a day. It was a fun project and well worth it.
