I have a bunch of old USA made optics. B&L, Argus, Unertl, USGI binocs/etc. Can't help myself !
Recently I acquired a Unertl spotting scope with a 45 degree objective. Unertl made many straight and ninety degree spotters and the famous 100mm team scope, but I'm told very few of the 45's , maybe just one year. Anybody have an old catalog showing 'em ?
