Information on Hammered Dbl Barrel

[Ronald Gordon]

New to the forum, just looking for a little help in finding some information on a Parker with hammers. I cannot find any serial number or model number anywhere on the gun. However, the underside of both barrels has 2 car-touches with the number 17 in the middle. It also has "twist" stamped on the underside. On the top side of the gun between the 2 barrels is "Fine London Twist". Any information is greatly appreciated. Picture attached

It has Provisional Birmingham Proof as applied to the rough tube in use 1855-1904. The '17' means the original bores were .649-.654, or tight 16g.
English Parkers include William Parker who was a gunmaker from 1790 until 1840 and one of the forerunners of Parker, Field & Sons, High Holborn, London, 1841-1876. E.D. Parker shotguns were listed in the 1895 Clabrough & Golcher catalog.
You might post in focus high resolution images of every mark on the barrels and flats here.
