1) A very valid point and one well worth noting. Well brought up.
2) A possibility, but as far as I remember, Webley & Scott didn't do completely one-off bespoke specials, just limited edition specials to a set number -- and as you say, if Chris doesn't detail a .25 Vulcan in this arena, imho, that rules this option out, too?
3) Can't rule this out completely, because as the diameter of a Patriot, Omega, Vulcan Mk.II and Vulcan Mk.III barrel (not the Vulcan Mk.I however) are the same (just checked), this is feasible?
and ...
4) Although I'd like to somehow link the .25 Vulcan being discussed here to the Webley & Scott factory direct in some way (doing so appeals to my fondness for the factory that was), I think this may be the most likely, but as you say, photos will help carry this cyber conversation forward me thinks?
Good thread this, thoroughly enjoying it.
