A close up photo of the action would help.

Webley and Scott or one of the Incarnation
of the Webley and Scott brothers firms - they
kept changing the name !!!

I have one and they are great guns - well made, solid,
good shooters (that I have found).

Probably one of the best / strongest actions around.

I also have Army and Navy 50 Nitro's built
on Webley actions.
