I too am very interested in what the experts here have to say about these two Birmingham boxlocks!! Lagopus, et al??
My understanding (or lack thereof) was that there were some of these trade-supplied Birmingham guns that were quite good quality, and supplied by makers including Webley, Scott and Greener. And some not-so-good "game-keepers" guns were supplied as well. Engraving and well-fit/finished figured wood were indications of the better ones.
From what the pictures show these look pretty nice, and I'd be happy to carry either in the field. And I've not seen anything like them for $200 in recent years.
