I got the same gun a few years ago for $450, i've been debating for a while about redoing the carriage hardware witch is mostly all wrong, it shouldent have boxes on axles at all, cleaning rods should mount under carriage on bottom of cheeks, chains are totaly wrong. Cva used to make a perfect copy of an 1841 6pdr w/oak carriage, all propper hardware. Im on the lookout for one of those now.
