K-7 old fashioned case

Hi,

I recently bought a K-7 + 40mm Ltd to make it a really compact. Works wonders.

While I often walk just with the camera, no bag, sometimes I would feel more at ease if it was protected.

I remember my father used to have in his "pre-digital era" camera a leather case that was attached to the tripod's screw, the top of the case could be removed quite quickly.

Does anybody know if something like this exists for the K-7, preferably maintining the compact nature of the camera?

Thanks in advance.
