A Mamiya!
Sadly, not a 645 or a 67, but a tiny, cute 135 rangefinder, called, perhaps not surprisingly, the 135. It's in 'mint' condition (not arrived yet) and was mine for the princely sum of £10. And because it's not a 67, I can chuck it in my overnight bag on my next few business trips. I'm now looking forward to Stockholm and Zurich even more than usual.
