These are not mine, but an old Navy buddy of mine asked me. I have emailed B&L and Bushnell but no answer. He has a pair of WWII vintage binoculars inscribed " Bausch and Lomb Binoculars US Navy MK 1 Mod 0 SN 107632 1942". Since both our fathers served in the Navy and Army in WWII, he wants to know what ship were these binos on during and after the war. Any help would be greatly appreciated.
