Thanks guys. I looked at the barrel bands that look brass like. It just doesn't look right with a blued barrel. Also, look at the nose. It's flat without a nosecap. Now, some early Brown Bess didn't have nosecaps, but this looks so square that it doesn't look real.
Also, it doesn't look like it has a lock. Could it be a breechloader? Still, I know of no breech loading musket that looks like the one used in the robbery.
Like yourselves, I think it is a replica toy.
