I Found this set of antique binoculars in a small town antique shop, California MO. Still with the original case. The glasses look nearly new, nearly flawless black enamel coating, and black leather wrapped. The only wear is rub marks from setting in the case. The case itself is well intact, though the leather straps, buckle and hinge had dry rotted clean away! I drilled out the rivets and installed new leather.
I'm wondering if anyone has any information. The only markings on them are around the eye pieces, both say "Nautilus Achromatic" My search engines come up empty.
I'll have them at the muster. They work great. Seem to be around 12X. $85.
