I have a Webley and Scott wholesale catalogue of 1914 . The guns in question are pictured and decribed as, "London Pattern Side-Lock Ejectors, with leaf fences and intercepting safety sears. The action is stated to be;Patent Top Screw Treble Grip". The price is given as 61 pounds with 2.5 pounds extra for leaf fences.By comparison the W.&C.Scott, Imperial is listed at 82 pounds. I once owned a pair of Evans guns that were identical to those advertised excepting that they had single triggers. These guns were serial #85** made in 1906. The guns offered for sale have lower serial numbers and are likely older.
