The original proofs were London, and the second Birmingham proofs are clearly stamped over the 'Siemen Steel'. I can't date the London Proof
The Crowned BNP (Birmingham Nitro Proof), and the .729" are 54' - 89' and the mark in the lower L is the Birmingham date code used 50' - 74'

It looks like an "M" on the left, and a "B" on the right, with a "1" at the bottom.

3 1/4 Tons is for a max. service load of < 10,000 psi

Higher than a lot of English guns, and at least it's got 2 3/4" chamber.
