Trying to understand what I'm seen from this 1897 shotgun:

I think there are original Birmingham Proofs from 1897 -1904
13 bore - 12/c - right barrel cylinder; left barrel choke

I think it was reproofed on London 1954-1989.
.728" - 2 1/2" chamber - 3 tons

But what are the other two marks?
"Crown over R" - Liège? I though "R" was for rifle.
"LP over 87" - ????

And this is the water table / action flats. First mark is Birmingham proof. Is the other Crown over CP?
