Might Help While researching this I came across this bit of info on the GP. GP is is for Gaffer or General purpose shotgun. According to Greeners book the exact number of GP shotguns made is impossible to be determined as the serial numbers of these shotguns were not recorded until 1968.

If your gun is a Police gun then the serial number look up I did for you is correct. If your gun is a GP then it's not possible to determine the date made by serial number. Two models of GP are referenced.

Apr 9, 2018 - The Historical Guns by W.W.Greener. J V Needham 1874 patent type self-acting ejector shotgun made by W W Greener. Fine Cased Engraved. Jun 02, 2012  According to Greeners book the exact number of GP shotguns made is impossible to be determined as the serial numbers of these shotguns were not recorded untill 1968. (serial number 417XX) by W. Greener of England. 44,000 of these went to Egypt (serial numbers 1001 through 45000), and the subsequent 15,846 went to colonial police.

Standard model has no checkering and a barrel band. The second model had a better finish, checkering and looked more like a sporting weapon, The Greener Story by Graham Greener has a lot more on this gun and other Greener arms. The book is a bit spendy but I have found it quite useful in my Martini hobby. There are contradictions in the book. The text makes no mention of a MK designation in GP's.

It refers to the checkered version as Model number 2. You should be able to look at the side of the action and see what it says to determine if you have GP or a police gun.

Serial numbers between that year's beginning serial number and the next fall into the same year. Search for your engine horsepower on the to find the beginning serial number for the range that includes your engine.' Your other option is to take the serial number to an authorized Merc marine eager and they can look it up for you.

Seen my Uncle's hammer 10ga double that he bought back in the 50's. He used it with modern factory 2 7/8 inch loads to about 1970 when one hammer spring failed. Looks like reblued fluid steel to me. If I remember right, top rib marked 'W W Greener and Son works Birmingham'. Barrel marked with crossed sceptres with crown on top and crown with double scriped B's (Birmingham proofs).

118 or 11.8 over 12m (both barrels) Not for Ball on left. Some scroll engraving. Serial Number 185**. Looking for date of manufacture and possibly replacement hammer spring.

He bought it when he was a teenager and shot a lot of pheasant, duck, and geese with it despite an area of barrel dents about 2/3 the way up. Mmd modeli kaneki ken. Otherwise the barrels look good no pitting. But he had to fix the stock in high school wood shop when he fired both barrels at once. Learned not to do that again.

He said duck hunting everyone knew when he shot because they could hear the barrels ring. A lot of factory nitro loads went thru it.
