I may well be wrong. I have a book with trade marks and proof marks that lists the winged bullet over W&S as being a registered Webley and Scott trade mark. I wouldn't be surprised if it was wrong though. It also shows the winged bullet alone as being a Webley and Scott trademark and your catalog proves otherwise.

Don't get me wrong, I like your shotgun a lot. The engraving and style reminds me of an early hammerless 10 gauge Army Navy CSL that I missed out on years ago. The time I spent finding out it was made by P. Webley and Son cost me the chance to buy it. One of the few that I regret missing out on.

I think that trade marks have to be re-registered every so often. Could you check and see what information the book gives on the mark. Webley made pistols long before the merger and in the catalog there is an interesting notation above the logo. I post a pic. Read the two lines right over the logo.

The book is "Gunmarks"by David Byron. I doesn't go into any detail on any of the proof or trademarks in the book. Just a diagram and one sentence for each. It has three versions of the Webley winged bullet. The cavity back one you have with trade and mark on either side and W&S below. One with more upright wings with a wide groove just back from the round nose which makes it look almost like a shotgun slug. It just has W&S below. The third is round nose bullet with several grease grooves and no letters. There is also the London Tower trade mark, the Webley in an oval, and the hand cuffed hands with Webleys above and M.R. below.
