Colin- you did an exemplary job on this one - too. I do prefer the British styling. It looks very much like the punt gun in Greener's book. Wonderful!
The only negative I can see, is one of personal taste. I would have preferred slightly rounded sides at the breech or a shorter octagonal section. Just the same, it's beautiful.
Congratulations on a job well done. Guess BigDog is going to have to buy this one, too, to match his other two, 2 bores - or is he already the new 'owner'?

12.8 drams is a fairly light load, I guess. What did it chrongraph?

Hey Bigdog - any comments?
