Yeah, the Scullys have seemed to go away completely...
Based on the (203) area code mentioned in that ad, I'd say this was more around 1962-63, when area codes were first mentioned in print (though the system itself dated as far back as 1951). I'd rate the Model 601 lathe as among my favorites - this would have had the following dimensions:
- Lead-in grooves: 7.625, 14.729167 and 32.3125 lpi
(also used for "spread" grooves to go from one track to another; last two also used for "catch" grooves after the lead-out but before entering the concentric locked groove)
- Lead-out grooves: 4.17 and 2.14 lpi
Yes, this ad would have to date at least before 1963-64, since there's no ZIP code listed for the address, but rather a postal zone listed ("Bridgeport 8, Connecticut", 8 being the zone), postal zones being ZIP code's predecessor (at least for large cities) until USPS introduced ZIPs in 1963.
Beautiful artwork for this ad, though :).
Another thing about the company: As of 1950 (when their first automatic pitch/depth control lathe was first introduced), the corporate name was Scully Machine Co. - I can't say at what point they became SRIC.
A 1975 classified ad in one of the engineers' trade magazines - from United Western Studios in Hollywood, no less - mentioned a Scully 503 lathe and noted that that model lathe likewise had variable pitch/depth controls. Probably the one introduced in 1950, with features later carried over to the 601?
