Greetings this is my greatest find yet!!! I got these on my birthday at fleamarket for 10$ the seller clearly did not realize they were military nor that they were Japanese. Which of course I respect them for that They work perfectly, also I did some research but could not find much. The company that made them is Yashima, which became or made yashica (camera comapny) in 1948. Under that is tokyo then the serial # 73357 then JES b9 or b5.
On the right it has 6 x 9.3 degrees. Um follows typical Japenese design ect. So my questions are;
is it late war?
Is it authentic Japanese ww2?
what is it worth?
