Not cap and ball, but...
I just found this Colt New Police/Police Positive in .32 Smith & Wesson (not .32 Colt). All original, made in 1908. I just got some brass, a bullet mold and dies and hope to try it out this week.
I got lucky again - about the same price as a used cap and ball revolver.
How can I shrink the pic? I used TinyPics.
