Lee, The Nov 84 date is based on the s/n/date chart in Supica's SCS&W, so until Roy catches up, and it's lettered, there's no way to know the accuracy of the Nov 1984 date. The gun is clearly stamped model 60 with no dash suffix, and is identical to the photo posted by dwf6666 with the exception of having checked wood grips instead of the goodyears.
I suppose incorrect model stamping sometimes occurs at the factory and is another possibility that the -1 was omitted in error. Anyway, my curiosity is toward finding out if this may be a model 60 CST produced prior to the Ashland run or simply an example that strays outside the block of ALU serial numbers known to be from the Ashland Sports batch.
