It's a later than 1965 GC1 then. Mine has 5/16/1962 etched on the corner castings. It came with Monarch standard rails and all you need to do is look at the original Brunswick Owners and Service manuals that will tell you when the "SuperSpeed" rail were introduced.... easy to find info. But the Artemis Intercontinental No. 66 rails are a direct replacement for the Monarch rails on a Gold Crown without any modifications needed. Brunswick does not keep or have any records on when any GC table was made. I actually replaced the skirts on my table with skirts off of a GC 2 because I didn't like the fiberglass parts on the early GC1 tables... The only real way to identify GC 1 & 2 tables for sure is the score counters are much larger and flat to the table. But dating manufacture is impossible without the original receipt and shipping label.
Same cushions on the 2 sets of Anniversary rails I have....before the GC'S were even built
