My little mystery - bird pendant with unusual hallmarks

Your pictures are far too large to see comfortably. Please edit your post and replace them with smaller ones. For pictures which use site storage we have a maximum dimension of 500 pixels and for embedded pictures you should be aiming for something not too much bigger than that.

I note also that you have posted this query on another forum - I think it far more likely that you will get an answer there as I fear that we do not have very many active contributors on this site.
