One Pentax (Pentax only) film camera is what you are allowed to keep and use for the rest of your days.
One single (of any supported or adapted mount) lens is what you are allowed to mount to that camera.
Which will it be? You may only keep one. Make your choice.

*EDIT - this isn't limited to what you currently have, but it is limited to a real-world scenario. E.g. The eventual faults each camera has will eventually occur. This is not a perfect-world hypothetical in which your favorite camera works forever. This is "choose one and live with it in the real world".
