Off the cuff, nitro proofed at Birmingham proof house. The internet gun club has a (paid) service by which you can check the provenance of many British guns via serial numbers, though I doubt they'll have much info on a Midland.

YES it is . Its Nitro . But according to museun@gunroof .com BP refers as a Black Powder it not stands for Birmingham Proof marks and 15/-1 for 14 bore (some of said that its a tight 16 bore) . Respected sir if this gun is a 14 or tight 16 bore (according of some member of internet gun club and others)then how the 12 guage cartiges are easily fit in it , because dealer me the demo. 14 and 16 bore having the slim(by dya)cartiges. The price of the gun is 85000 and. When I asked for billing his replied that he billed 15000 for this gun.
