I love locks like that, Bob. That doesn't make them prettier in your eyes, I suppose. You also have to look beyond the lock to the style of gunstock the lock demands.
I spoke with Barbie and Jim a few months ago, expressing interest in that early round faced Germanic lock. Jim said it was in limited production, as HE was the assembler until all the proper tooling had been made up.
A hand made lock is a lot of work. But making a new lock production design is a labor of Hercules. Tooling up all the molds to make a new lock is a tremendous labor. Once the molds are tuned to produce good parts, then the drill and assembly jigs must be made before the lock can be put into production.
Skiing, trout fishing and lawn mowing also have an impact on production when you're a small workshop.
