So going through some of my grandfather's things, we happened upon this old muzzleloader. It is not in shootable condition, nor do I think it could ever be given some of the damage.
However, I would like to get a better idea of what it is/was and it's origins. There are a few rollmarks, but my searching has come up with nothing.
The best I can figure, it is a Hawken Style .50 of some sort.
There looks to be a manufacturer roll mark ending with "ER" in a banner/scroll on the trigger assembly
On the barrel, there is an "R W M" roll mark which searching has indicated could be indicative of a Government/Military Inspection marking, however all the examples I found on the web were accompanied by an anchor...none here to be found.
Not much to go with on markings, but I figured there is enough that someone who actually knows what they are looking at could assist in identifying. Thanks for any assistance with this endeavor!
