Genuine Canon Motor Drive opening cover for the A-1, AE-1 and AE-1 Program film cameras. Made by Canon Japan. Many of these covers are new (Mint-), though I have graded them as used. These new cover parts were kept loose in a parts envelope.  A technician would pull the envelope and may hold 2 or 3 covers, pick 1 and drop the rest back in the envelope. The Mint minus covers are the cleanest I have. Condition graded as follows, MINT Minus. New part though may have a small mark from handling which will take a close examination to see. Nearly if not impossible to resolve any flaw in the image shown when using a Macro lens and a Canon digital. USED - EX Plus Looks to me like this cover was removed/installed once maybe 2 times very carefully. USED - EX Looks to me like this cover was removed/installed 2 or more times. Not really ugly yet. USED - EX Minus This is where these covers start to look a little used. Removed 2 times maybe carefully then not so much. USED - Value This is where these covers start to look a more used. Removed a few times maybe carefully then not so much. Will have some more nicks in the slot and/or scratches on the surface. Lastly,  you may have a black Canon A-series camera and want a black MD cover. Canon may have made them, I never saw a part # listed in any Canon parts catalog or one installed on the A-1 or the AE-1.
