I recently discovered my mother had an old Asahi Pentax AOC camera kept in a closet that she does not use anymore, it is also known as the Asahi Pentax AP or Original. There are currently 2 problems with it. 1. It currently only has a Tokina telephoto lens on it and the original lens cannot be located. 2. The shutter and viewer is not working completely in synch, at least as far as I can tell. Currently, it has no film in it. Q1: What type of lens (original type if possible) should I be seeking for this camera? Q2: Is there somewhere I can get the shutter repaired in the United States?
