I still have my Record crankset from the time when I ordered my 1993 Litespeed Classic. I believe my 1992/93 crankset is engraved. My C Record track cranks are engraved and I believe that to be from the late 80's or early 90's.
I'll check to see as soon as I get home from work this evening.
I must say they are beautiful cranks though, especially with the engravings.....
