Hi Gents, I have arrived here after much searching of the web, I wonder if you can help me out with some information about, what to me is, an enigmatic gun.
It is a side by side, back action hammer, underlever with 30" damask barrels.
It has rebound locks and a steel butt plate, it has Birmingham proofing and is marked with the choke size, I would guess at a date of around 1887.

The bit that I cannot get is the maker, the only markings on the lock plates are W.M & G.... that is it, nothing more, I have searched and searched for a maker that used this mark and have found nothing, can anyone here shed some light for me?
