Well spotted. I'm not sure whether to call it a Fenman or an Evo. It's certainly in a Fenman stock, but has dovetails rather than fixed mounts, and was sold to me as a Fenman. The s/n makes it seem to be rather late to be a "real" Fenman, so what differences are there between what you see in the photos and an older Fenman (or newer Evo) action?
