Used 360mm on Technika board. I purchased this from the original owner in NYC back in 1982. I have used it sparingly. It is in the same condition as when I got it. Shutter is right (the second setting needs a few cocks to get it right).... that's what she said. Glass is clean, no rubbing marks or haze. $425 and I will pick up the priority mail within the US. Paypal will work.
