I have done a little detective work and here is what I have come up with. Serial number on the frame is CF03594. Production number on the Dia Compe brakes is 07 86.
Based on the codes given for Nishiki serial numbers I was thinking it was possibly from 1976 (only because it states production is pre 1985 on Nishiki), but this seems too old. But now with the brake code I am thinking 1986 would be the date.
I will look for a few more part codes and see if I can confirm this.
