3.0 ?
Bob
By the time the Craftsman grey saws came out, Sears was more into standardization of parts. 3.0 in the charts Gregg just posted refers to a chromed? bore of 1.750, slightly bigger than a 3.0. Many, if not all, of the red ones were repaired with the 3.7 jug, so if you owned a 3.4 you were supersized for free under warranty or if you brought there for repair. Our friend Eccentric, having worked there, will confirm or deny this. So the only difference in saws could have been bar size in the grey ones, now I wish the catalog graveyard was still available.
