I have a member who has a Colt Signature Seris Model 51 cap and ball for sell. Comes with a few other items such as a case and such. This is an actual Colt revolver but made recently.
If interested let me know and I'll put you in touch the the person. The asking price is $350 or b.o.

This pistol probably won't last long....I am considering it myself but am tied up buying parts for the %#^@ cannon.
