As I said on the other site.

I think it is/was a Baker. The lock and receiver angles means it is probably a Lefever or Baker. However if you look at the lock configuration and pin locations as well as the screw right at the area the lockplate expands from the receiver it looks like a Baker pattern.

If someone can find a Lefever with the same pin/screw locations on the lockplate I'd like to see it.
