Sounds like a date code not a proof mark.

Crossed swords Birmingham date code 1950-74, B at right and letter at left denoting year B=1951 C=1952 and so on

 

inspectors number was usually underneath

 

so proof dated 1951

 

 

 

the proof mark will be a crown with thick letters underneath

Between the swords on each side there looks to be a "B", on the bottom is the "1" that you could see. There is a crown over BP, a crown over BV and a crown over NP. In a large diamond is a "12" over a small "c". The left barrel is marked as "13/1" and on the right is a "12". Both are marked as 2 1/2 for the chamber length, and 1 and 1/8 oz. They are also marked as nitro proof. On the actual barrels is "Made in England" , and the crown over "BP" interlaced. I just realised on the flat of the barrel appears to be a "k" but it has been stamped sideways. On the rib is "R. Robinson (gunmakers) Ltd. Hull".

BV is the Birmingham View mark since 1904

BP is the Birmingham definitive nitro proof for all guns since 1904

 

is it BNP or def BP?
