Hello - I was given a boxed Webley Senior pistol and am looking to sell it. I have had a look online but am having trouble dating mine as there is no serial number I can find and I have no experience with old pistols. It seems in remarkably good condition and comes with it's box and even the original receipt was inside for £7-10shillings. I've done my best with the pictures in macro mode, most of the apparent blemishes are dust, fingerprints and old grease rather than scratches etc. If anyone could point me towards a reasonable valuation I'd be most grateful

Here is a link to the pictures
