My pentax 110 back door broke and I would appreciate help with the following: 1) Does anybody know if the door (and only the door) can be replaced easily with another door taken off an identical camera I may get from ebay?. 2) Can somebody help me get the schematics or the exploded drawing of the door assembly? (the whole repair & parts manual would be great) 3) Are the doors on the regular 110 and the 110 Super interchangeable? Thanks Leo
