Asahi pentax bellows

[imkap]

I'd like to buy a macro bellows, this one seems nice although seller claims it has 49mm diameter screw in rings (not m42), I'll find a way to connect the camera and the objective, no problem.
I'm just wondering if anyone had any experience with this one, or would recommend another product or this should be good.
The price is around 60€, which seems a bit lower than on ebay.
It has a focusing rail and looks minty...

It is an Asahi pentax Auto bellows, here is a pic:


Just got a mint Zeiss tessar 50mm 2.8 (the black version) and it seems to work nice with extension rings, so I'm curious to see how it will work with bellows... I've seen some great images made with this objective on the Internet.

Thanks

I would guess that the 49mm is a reversing ring

My thought too, but I don't understand why on both sides... Although maybe the seller didn't measure both
