I should be joining this group shortly. I have a 39 Summitar with the weird apertures and just picked up a CLA'd '39 Leica II body for it for $200 US. Youxin has seen the lens and told me it's a little "off" with the focus, which he says is normal for those lenses, so I'm going to sent it all to him and he's going to match them together for me. I'm stoked, can't wait!
