This gun is probably Belgian or Birmingham made. The triggers and guard are too thick and not elegant. The engraving is typically Belgian. The real proof would be to see if the name and address are on the barrel, spelled correctly, and the proof marks are right. Also, it would be nice to see the underside of the locks.

I have worked on many Purdeys in my time and if this is the real deal, it will be my first time to see one of such poor quality. Caveat, they are poor pictures making if difficult to discern for sure.
