Parker England?

[Mike Franzen]

Never seen that particular brand but it does kind of look like a Parker. Back in the day a lot of guns came from Europe bearing the Parker name. I would surmise many a yokel were separated from their money by some businessmen or gun trader who swore it was the real deal.

It does carry a Birmingham proof mark and we might be able to provide more information with a full size close up image of the barrel flats.

E.D. Parker shotguns were listed in the 1895 Clabrough & Golcher catalog.
William Parker was a gunmaker from 1790 until 1840 and one of the forerunners of Parker, Field & Sons, High Holborn, London, 1841-1876.
The lowest grade guns marketed by P. Webley were sold under the name of Thomas Parker, London c. 1900-1920.

I agree however that it appears to be a lower grade "knockoff" without connection to Parker Bros.
