Mamiya C330 S Medium Format Camera Body Only Not Working

Serial Number: W305088.

It shows signs of use.

The film counter resets to 10 instead of 0. If you are shooting 120 film, you start at 10 and after two shots it reaches 12 and the camera thinks the entire roll was shot.

Extending the bellows is a little noisy at the beginning but the bellows is intact and works well.

All other camera functions work well. Shutter fires and film advances.
