I think this one was some sort of industrial lens. It's on Grimes list with no way to fit a shutter to it. F/5.6 or so. No other stop. For awhile somebody from Europe kept trying to peddle one. The price was high enough but the shipping would make you faint.
Last week I was tempted by a Soviet built 5x7 [well the metric version] Bidding for the camera started very low but shipping was about $100. Worst part? That was shipping within the EU. To North America it was to be quoted.
