The Numrich parts lsits and schematoics are not always exactly correct. there were many versions of this family of shotguns. THe Model 60 was designed developped and tooled for Sears at Sears expense and was sold exclusively by Sears for several years before it evolved in to the Model 66 which is very similar but different. High Stadanrd was not selling any Model 60 or identical model under the High Standard name. THe High Standard Supermatic C-100 was a contemporary of teh Model 66 and is very similar to that model but a little different.
The rollmark drawing date preceedes the actual manufacturing date by an unknown length of time. There were several versions of the Model 60 as distinguished by the reference numbe 583.xxx. Some variations had slightly different parts and others had mostly cosmetic or feature differences.
The only good way to date the gun is to see if it is late enough to have an assembly date code on teh barrel just forward of the receiver in the form of two upper case letters. Assemlby date codes did not appear until December 1956.
