Found this past weekend at a camera show for about $20. A Zenobia by Daiichi Kogaku. It's a 6x4.5 format folder with 75mm f/3.5 lens (Tessar type) with shutter from 1 sec to 1/500 plus B and working nicely. Focus working smoothly. Bellows look very good. Lens was cloudy/dirty. I pulled the rear group and it cleaned up pretty easily. It's clean enough to use now but I will clean the front group too. Camera opens and closes easily. Chrome is bright and sparkles and I haven't even polished that part up yet. Solid feel and heft. Overall, very nice condition for a 50-year old camera. Needs one little strip of leather on the back release latch area (easy). Came with original worn case. I was going to sell it but it's looking like such a little gem, I think I'll keep it. Vintage Japanese cameras are tops for long term usability in my book!
