Thank you Blair, Curt, and Craig for your insight and depth of knowledge. I guess this is how using too much assumption and too little research can land you in the hot house! Because Flayderman listed Flagg and Waters as contractors for the M1842 and other examples I found, led me to believe these brass mounted muskets were more common. It also made sense to me that few of these muskets would have survived to end up on a museum wall/collection do to the fact that soon after being re-worked/repaired they would have gone right back into service. Much like sky blue trousers. They were one of the most produced items, but the rarest to find now like new.
