I am not sure that I ever posted the additional information that Mr.Greener was kind to share.

This gun "was started the 16th of May, 1907 and finished on 12th September of the same year. It has a Facile Princeps type action and is an ejector model grade "G 3". It was made to the same specification as gun no. 54812 so it may be the no. 2 gun of a composed pair but it is not recorded as such since pairing is usually recorded. It is a 10 bore with 30 inch Sandvik steel barrels. Stock dimensions when made were 3-1/8 by 1-5/8 by 14-3/8, 14-1/4 and 14-3/4 inches, half pistol hand, normal cast of 3/16 of an inch. It was engraved with scrolls by Horrocks. The G3 grade is essentially a 'best' gun and cost 45 guineas when originally made. It was sold to 'National', probably an agent or gunshop.'

How kind of Mr. Greener to help with my inquiry.
