... This brings up an interesting point in that his is the third Large Gibbs I have worked on and they have all had similar, but slightly different engraving patterns.
Barry:
Yes, same pattern, but there's always a slight difference that you have to look for to notice. The pattern is Webley's, not Gibbs'.
This rifle is a Webley A & W C 1st Quality model, built for Gibbs. Webley built many double rifles for various retailers, and these rifles were almost always "bought in" complete, as opposed to being stocked and finished by the retailers. You'll find the same pattern on the same model rifle from other retailers like William Evans, Army & Navy, etc., as well as 1st quality models that Webley & Scott retailed themselves. It's Webley's standard engraving pattern for that model.
Congratulations to you and Jerry. It's beautiful work.
