That deep red looks good East Hill!
Mine is an '83 (KC 32018) and all the components appear original except the wheelset. The seller tried to do a bait and switch and sent me some junk wheels that had dried mud caked in the axles so hard there was no way a skewer had been in them for years. The set shown in the auction was on another bike a week later. The replacement wheelset he sent has a 6D code on the Suzue hubs while all the other component date codes are from mid '83. I like how the gold anodized rims match the rest of the bike, so no gripes here.
Original components with date codes:
SR seatpost - F 83
Sugino RT crankset - GC
SR Sakae Custom stem and bars - J 83
Suntour ARX Front DR - ZC
Suntour ARX Rear DR - ZH
Diacompe 500 Brakes - 0983 M
Non-original parts:
Suzue hubs 6D with Araya 700c gold alloy rims and Shimano Z2012 6 sp freewheel.
Next seat and Nashbar pedals.
BTW This 52cm bike is too small for me so will be for sale soon.
