One of Messer's Webley's .As stamped with the Anson & Deeley patent on the action date is about right .
I would suspect it has been restocked and I am a little curious about the additional extractor stop pin, one in the back lump and one in the extension also to the what appears to be spring around the extractor leg .I also notice there are two sets of bore size's on the proof marks 12 & 13 over 1 but can not make out the rest so possible reproof for Nitro at an early date ?
