These are 1st generation Conquests and are certainly worth the current asking price.
OP it might help to let folks know if this bin is threaded for a 1/4x20 adapter stud or not. I don't recall, but it would be under that cap between the objective lenses.
Interesting. I think that was for a zeiss proprietary tripod adapter but I can't recall. Either way, that is still a good deal for a solid set of bins.
