Doc:

I'm not sure how many pre-war hammerless Webley DRs are out there. Webley's rifle records don't survive, which is part of the reason that I began trying to reconstruct a table some years ago, and there are some holes...

First off, Webley's rifles were numbered separately from their other production. Yes, very roughly 10,000 to 14,000 SN range 1900 to 1927, or a total of 4000 rifles during that period. You need to keep in mind though that this INCLUDES Webley's Model 1897 and 1902 falling block single shots, and other rifles as well, although production of those models doesn't seem to have lasted very long. Bizarre that the latest Webley built DR I've ever found is late 1927, in the high 13,XXX range. I'm not saying that later guns don't exist but, if they do, they're very, very rare.

Webley made double rifles on five dedicated double rifle (not shotgun) actions - HC (Hammer Cordite, available with either top lever or Jones UL); PHV-2 ("Plain model" Hammer, with either top lever or Jones UL); PHV-1 ("plain" boxlock - but because the overwhelming majority of Webley's production was for others, some PHV-1s ended up as some of their fanciest guns); A & W C (typically a higher grade boxlock model, but not always); W & R C (Webley's sidelock model).

All of these can be found in all grades, as they built what was ordered. Excluding handgun production, Webley stated that 90% of their guns ended up with someone else's name on them. For sure this is true of the double rifles. Of the fifty odd Webley double rifles I have written notes on, only four bear Webley's name. Even though I don't have my notes with me, I can remember what they are: PHV-1s all, in .250 Savage, .280 Rimless, and two .450/.400 3 1/4" Nitros. As for the most common nitro caliber, .450/.400 hands down, no contest. Small and medium bores are more common than you might think.

Yes, a few years ago the .400s were numerous enough that they could be had for less money. The market has since soaked up the nice ones and they're very difficult to find. When they do turn up, they aren't cheap anymore.
