We've discussed the "second run" of L46's made in 1963-64. Some of them were Deluxes in some rather scarce calibers like 7x33 and .25-20. However, I don't know if anyone is aware of a "second run" of L57's. I don't know how many might have been made and haven't been able to comprehensively sift through the records, but I have found twenty-five of them, all in .243, made in December of 1965. That's six years after the L579 supposedly made the L57 obsolete. Only one of these 25 was distributed in 1965 (since they were made only in December of that year that is understandable). So it is the only one with a serial number which can be checked against the inspection records. It checks out with a 1965 date. (See the attachments below). There is also a single L57 showing in the shipping records in 1967. It bears a serial number consistent with the L57's (9,000's), but it is listed in the inspection records as an L579. Hard to know which it actually is, but it is a Heavy Barrel. It seems pretty amazing that parts for the L57 would sit around the factory for six years before being made into a rifle, but we've found screwier things with Sakos before!
