Canon started production of the A1 (one of its top models of the time)in 1978 and this carried on until 1985.
We have been repairing these since the very early 1980’s.
This one came in this week in virtually unmarked condition. It just needed a service and all the light seals replaced, the speeds needed slight adjustments and the meter recalibration.
Remarkable for a 35 ish year old.
