Most likely a Mk III in caliber .38 S&W (NOT .38 Special) Depending on condition and originality, value could be anywhere from $100 to $300. Many were imported into the US after WW 2, and were shortened to snub nosed barrel lengths- values of these are much less- and despite the war stories, there WAS no military issue snub nosed Webley, for tankers or commandos.
Butt or inside the crane area

Most British officers carried the British Webley .38. -Some had a .455 version instead.
Where can you buy .38 rimfire ammunition from
yes
A good starting point would be to contact Webley & Scott- they are still in business, have a website and an email contact on their site. There are at least 3 handguns that may (at a stretch) fall into the category of a Webley & Scott .38 pistol- the Webley-Fosberry Automatic REVOLVER (somewhere between a revolver and an auto pistol) the Webley Metropolitan Police auto pistol in .380- but I expect you are looking at the W&S Military and Police in .38 Auto. These are rather scarce, made in the early 1900s, and only for a brief time. Sales seems to fall in the $2500-$3000 range. See link below for a picture-
Never heard of a PB 38
its a 38.cal hand gun. so YES!!
