Hi,

difficult one - any hints like objective diameter and maybe magnification (compared to other instruments of known magnification). From comparison I would say less than 40mm objective diameter - 30 or 35?

It has 35mm at the end. Maybe it is something like 7x35 or 8x35. Mason 7x35 looks very similar but what i read it was made in japan not korea.
 
Probably 7x35, single blue coated. Perhaps 1960s.
This is a lot better than the extra wide angle Korean binoculars that were very shoddy around 1970s.
The binocular shown seems to be a regular Porro with perhaps 3 element eyepieces.
May be quite good if well aligned and clean inside.
Perhaps £15 in good clean condition.
 
Thanks! Optics is very good but it is not aligned correctly.
I completely disassemble it then i cllean it. I tried it to align but i cant do it for 100% because I did it for the first time.

Not to worry; there are plenty of long-standing "professionals" out here who can't clinically collimate a binocular either.

I am saddened, though, by the number of people I hear about every year who undertake the repair without considering the critical task that awaits its completion. :cat:

Good luck
