Is it a dark red? I've seen one red one with all Japanese stuff on it, but still with the pressed-in BB. Can't recall if it was a Sebring, but it did have a model name. Customer's bike--he had broken the snap ring spindle (at the snap ring groove--d'oh!), which I replaced with a Klein part.
Seemed to me it was newer than most of the Viscounts out there, so maybe 1978 or so. Check the date code on any original Shimano parts. It's two letters, first representing year: A = 1976, B = 1977, etc. Components may be a year older than the bike.
