Well here are some pics of three of my favourite Canon FD manual type 35mm cameras. The top three 35mm manual SLR's from Canon back in the day.
All three here work perfectly as designed and made by Canon respectively back in the day. Just some age old wear and tear, love kisses by their previous owners.
A-1 debut 1977
F-1n debut 1981
T-90 debut 1986.
The A-1 has the Motor Drive attached to it.
F-1n has the Ae Finder.
I'm a very happy camper
