Doc is suggesting that it is a fake (desi made) based on the stampings and markings on the gun as they do not seem to match the stampings on a real Webley.nd I wasn't able to follow the "stamping was wrong" comments that people have made. More light on that matter perhaps?
Here are photos of a Webley mark IV. Compare the phtos with your photos and see if you can see a difference.
