Interesting story and nice looking rifle! I've had dozens of Trapdoors over the years, but still have yet to get a carbine or a Bannerman. That one looks like it's a good mix of the two. I wouldn't mind getting one of those to just plink with.
very nice rifle, although I don't believe it's "near unissued" looks to me like a put together on a repro stock with fake cartouches. the stock looks way, way too good compared with the metal parts
and yes, they make fake cartouches, here is a example of one there are more other different ones
still it's a nice rifle
I would suggest leaving well enough alone. If the discoloration/blemish on Steve’s barrel doesn’t easily wipe away with a bit of oil and a soft, non abrasive cloth it makes no sense to resort to more aggressive techniques. The dark brown areas are clearly not recent or active spots of corrosion. It’s an age appropriate patina that is far more pleasing to the eye than the shiny areas that will result when the metal is scrubbed clean.Lightly rub the edge of a pure copper penny with some oil over the rust spot. Should take most if not all the rust off with no blemish.
