I got back to my friend's house and took measurements and pictures of the E. Dimick, St Louis rifle parts. Here are the barrel measurements and if you want pictures, you can PM me with your cell phone number or email address and I will send you what I have. The barrel is 36 inches long and the breech plug is 3/4", making a total of 36 3/4" barrel length. It measures .0940" at the breech and is tapered to .0900" at the muzzle. The breech plug appears to have been changed by someone, as it has not been filed to fit the hooked tang. The bore measures .375". The rib is 24" in length with 2 thimbles and there are two barrel lugs. The tennons are included in the parts. The following is a list of parts--butt plate, hooked tang, double set triggers, tennons, rear sight (looks like a buckhorn, but is actually a peep of sorts), lock (mainspring is missing), trigger guard, and toe plate. The front sight appears to be silver and is still on the barrel. The rear sight location has been moved, so there are two dovetails in the barrel, one filled. If you have any more questions, please ask. As I stated in the initial post, we are mainly trying to establish a value for these parts and any help will be appreciated.
