Gentlemen,
I was wondering if anyone knowledgeable about British/Commonwealth fittings on American tanks could perhaps help me. In the well known photo of an M10 tank destroyer in Polish service there is a device mounted on the right hand side of the turret. Initially, I thought it was another .30 Browning machine gun, but it looks like some kind of sighting equipment. Does anyone know for sure? Thanks in advance for any possible help in this matter. Regards, MK
