Pentax MZ-7 mirror motor gear repairer?

I have a virtually unused, absolutely immaculate, MZ-7, that seems to have the broken mirror motor gear issue.

The mirror stays up all the time.

Anyone suggest where I can get a quote for it's repair, please? Seems such a shame to just throw it away.

I had a look at a tear down for a similar camera that exhibits a similar issue (also with the mirror motor gear) and it looks like an exceptionally involved repair.

I’ll suggest Asahi Photo but I have a feeling that the cost of repair would be fairly large.

The repair is very difficult as you need to take the camera apart completely. The gear is right at the centre. I took an MZ-5 apart a few years ago, having ordered replacement brass cogs from a company in Poland, but I wasn't able to do the repair or put the camera back together again. It's just not worth it.

Thanks guys. The camera is truly mint, but I suspect it'll be uneconomic to repair, if indeed it's actually repairable.

Well, Asahi Photo think they can repair it, and have given me a ball park quote of just under £100+vat.

Head says don't do it, heart says ignore the head.

Heart is winning ATM.

When your heart makes the decision for you don't forget to check whether the replacement cogs are Brass or Plastic

They're not brass apparently, but they've never had a return or complaint in the 7 or 8 years they've been repairing MZ cameras. But, I am aware of the risk.
