Dowell's The Webley Story captions the picture of the MkVI with shoulder stock "1916 Model with detachable shoulder stock as used on parachute flare pistol. (my italics). There is no evidence that pistols were ever fitted with the shoulder stock in use and certainly they were never issued that way. Have collectors over the years fitted the shoulder stock to pistols? Absolutely. As to the bayonets, there were estimated to be less than 200 originally made. In 1968 when the W.W. Greener buildings were being emptied and demolished, parts for a few more were found. The parts were assembled into complete bayonets and sold on the collector market. There is debate in the hard core bayonet collector community whether the assembled ones should be called original or not. There have been several reproductions out of India ( I have one) that range from pretty good copies to ones that are obvious reproductions. I looked on Simpson's site and couldn't find the piece shown in the original post. Therefore I can't comment on the bayonet they listed. I have not had any personal dealings with that company so I am by no means imputing unethical practices to them, but in general if you believe that dealers, even big name high priced ones, don't both knowingly and unknowingly sell fakes/reproductions as legitimate I believe you are naive. I did notice Simpson's list a German WWII uniform with "may be reproduction" as part of the description but priced as a legitimate period piece. To me that kind of wording is a big red flag. Call me cynical, but I view those as weasel words that lets them tell an unhappy buyer "Well we said it "might" be a repro."
