old model Ruger single six :rear sight: Novak Cut

[butcherboy]

does anyone know what are the dimensions of the old model ruger single six rear sight dovetail? are they Novac Cut and what exactly is a novac cut. thanks

Novac is a sight maker and a receiver cut for a Novac just means it is cut for that sight. If the dovetail in an OM Single Six was a match for a Novac sight it would be just a coincidence.
