I might be able to help you out. If you can tell me where to find an undamaged set of Dominion aluminum handled picks. Preferably in their original case.
The Fed Corp "Cobra" was something unique at the time of it's introduction. As you well know, the design has been copied ad infinitum for a number of years. The worst part of it is, many of the newer designs are just as capable as the Fed Corp pick, and I do believe cheaper.
Let me see what I can dig up for you.
