Not Sure.
I picked these up today. I wasn't sure what to expect, but they are quite nice. A little dirty, but the glass is in great shape. They are a handy size. The views are nice, with a "warm" cast to them during the daytime in bright sunlight. The eyecups screw in and out and make a nice seal in my eye sockets so not much light gets in from the sides. I figured they would have Bk-7's but the pupil is completely round with no shadowy edges. I think they were made in 1967
