i have Yashinon macro 60mm lens that i've seen also branded mamiya sekor, so they probably had same manufacturer

Indeed, some of these 60mm macros are even marked "Tomioka", so in this case there is no doubt who made them.

i know, it's a case of cost effective production like in many cases where same manufacturer produced lenses for different camera makers

True. But the seller describes this as a museum piece, and I'm taking him at his word. I'm treating this as an exhibit created to enhance our knowledge, rather than a legitimate commercial opportunity. Wink

In all seriousness, the CWP isn't a terribly common camera, and it's even less common in good working order. And if we're prepared to concede that this is an unusual, desirable lens, it might be possible to justify two-thirds of the asking price - for a Mamiya collector, anyway.

(Maybe.)

Cheers,

Jon

One more item for collectors - Click here to see on Ebay
Look at a label ring and M/A switch - it is different than usual.

Plastic is broken off the A-M switch. I have a Mamiya Sekor 55/1.4, the rear element is flat or nearly so. My Chinon 55/1.4 is same. Yashinon 50/1.4 has a noticeably curved rear surface.

I know the plastic part of A/M switch is broken but I've meant its shape, more correctly a shape of the mount it sits on. Here is how it looks usually:

I see. I'll look over my lenses for that detail.
