Gentlemen, I have just returned from Vegas and perhaps can add some info to the "discussion". The gun in question has the identical pin placement as my Scott Monte Carlo B pigeon gun, circa 1910. The treatment of the fences is also a feature that I have seen on other Scott built guns sold by other "makers". The gun has been finished/engraved to a high standard and shows the quality of Scotts workmen regardless of what model it may have been.

Better to keep your mouth shut and be thought stupid,than open it and confirm.
