Need help to I.D. these Japanese Binoculars

[whitman75]

Hi there I'm new here and I recently aquired a few sets of Binocluars that I need help Identifying. These pair are Japanese made and besides whats written on them I have no clue what else they are. I was hoping to find out if what era they are from and if they have any value. They are in amazing condition but here is what I see written on them. Tower 10x50 below that a 6 with a small o above it also it says coated No. 10204. The last thing I see on them is it says made in Japan Ofuna. I hope that you will be able to help me answer some questions. thank you
