RINN CORP 54-6002 DXTTR III DENTAL X-RAY TRAINING MANNEQUIN DEXTER HEAD # 3520

Furthest back, mouth sits at rest without catching a ratchet point (Photograph 9), the ratchet device must be advanced several steps before the jaw actually moves, ratchet point shown in photograph 16. Jaw rests with the teeth slightly separated (Photograph 9) and opens to the maximum amount shown (Photograph 19). There would normally be two nylon cables on the head to secure it to a platform, the cables are missing photographs 10 and 11 as well as one of the plastic cap covers. The head has a round ball on the bottom that would mate with a holding device. Ball diameter is 0.9950".

There are some mounting pieces included with the device, but a side screw is missing from the assembly that prevents it from being complete. Without the side screwand metal part as shown in photograph 3, what would be chair placement mounts are not complete and would not be balanced.
