Just got my WWII M17 binoculars back!!! I got them for $20 at a garage sale. They had been dropped or something, no obvious damage but the erectors needed re-collimated so I sent them to Koehlers in IL. This is the 2nd pair I have had them fix. THey do top notch work at a reasonable price!! Have quick turn around also. Can't wait to get out and use them. They are the old B &L quality.
