Cannot find this mark

[catthegr8]

I'm trying to find the maker of a mark on a silver heart pendant. It is hollow and the piece that attaches to the necklace screws off and has a small piece that sticks out. A friend said that it might be from when belly dancers were popular and the hollow part held poison that the dancers could dip into and stab their victims.
I tried adding a picture of it but when I click on 'Img' it won't add a picture.

The mark shows in this order:
925 B (it might be P also) then a space with something I can't identify then 'MA'
