LET ME KNOW IF YOU KNOW MORE ABOUT THIS UNIT. For a 50+ year old piece, item is in pretty good condition. The bend in the description, as already stated, is pictured and is on one of objective lens barrels. Lens see through is very good and clear. Center focusing ring is nice and firm, moves smoothly.
The diopter adjustment ring right side is stiff and will probably require some minor force to free before lubrication.
