I'm still dark on GW because he dumped on my invention of regulation with a separate sight leaf for each barrel, switched by recoil inertia. Possibly he was referring to the Kodiak separate sights, which were changed manually, but I had sold a DB Winchester rifle to a well-known gun writer who made reference to my sight in an article.

OK, as a primary sight on a DG rifle, my sight added complexity and could be seen as an improvement to button-up boots. But I still think the last version, which looks just like extra leaves down the rib, has merit for long shots, sub-loads or non-regulated bullet weights.

Not the done thing, old chap? True, but we do put scopes on doubles and Robin Hood didn't use a compound bow.
