Hi everyone,
To sumarize, I was on location a few days ago to discover that the exposure button was broken of my pentax 6x7.
To bad, luckily I had a other broken body for spareparts, so I switched the broken parts with the working ones. I did this very carefully by the way, assisted by a guy that knows what he's doing when it comes to technical stuff.
After my little operation the pentax indeed worked again.

The new issue is that the counter does not move anymore. Film is 'walking' correctly, all seems fine except for that one thing.
We looked very concentrated but could not find the cause of this defect.

I was hoping someone around here knows a little about these camera's and can give me a hint on were to look. What could be wrong???????

thanks in advance, kind regards ~sam
