The Folmer & Schwing arrived today. Wow. Workmanship is incredible and it's *tight*. Smooth and silky focus using the big wooden knobs. Only problem is that there is no rib-lock channel in the back. I'll have to rout one if I want to use my S&S holders. I have an ancient holder with no rib, and the camera came with a no-name holder in fine shape that has a small rib moved far enough down the holder that it engages the inside of the back, not a channel. Kinda hate to make sawdust from this queen, but if I'm gonna burn Efke, I'll need all my holders. Scan of first image(s) to follow.
