Just found your post while doing research on the same bike. I found mine Sunday night while racing home to see the start of True Blood. Mine is Scarlet Red also, frame's in great shape just the name on top tube seems worn away to the white primer coat. I'm goona name her Sookie. I did a lil research the coaster brake was made up until 1982 as a cruiser only in Ice Blue. So the scarlet reds would be earlier they are no longer in the catalog by 1985. There were three speed versions they only came in in ice blue or peacock blue and white. Compact is the size, all compacts are 17.5" frames. there were racers, three speeds, I have that same bike took it out of the grabage. I'll post some pics tonight.
