No, A. & W. C. doesn't exactly roll off the tongue, does it? Not much better on a keyboard.

Its long been obvious to me that our tastes in double rifles substantially coincide. Yep, buy the face, not the name. Once you've learned to recognize the Webley's and the Leonard's, that cuts a wide enough swath. All that's left is determining fit, function, and condition. The name ca-ca gets silly. Saw a nice Holland .470 recently. PHV-1. Identical rifle to an Army and Navy that a buddy has. No difference at all in the level of finish (damned plain, but good). Although I can't be certain, I'm pretty sure that rifle was nothing more than sort of an unmarked "shot & regulated". I doubt Holland did anything more than cut the stock to the customer's dims and maybe tweak the regulation. You'll pay a lot extra to get the name though.

Yes, I prefer a doll's head extension, but a straight extension is OK, as long as there is some kind of rib extension to keep the barrels square to the face. Maybe just luck of the draw, but I've periodically seen DRs with most of the other top fastener types (cross bolt, hidden Holland type, etc.) that were off face, but not Webley screw grips.
