    Which lens has the 1-inch focal length? And is that the focal length or the back-focus?

    # 6 of 6 Last one for a while

    This one is simple, it has no markings that I can find with a light and a magnifier. Zilch

    It is 6" tall, Hood OD 3.5" 2 elements, cleaned up nicely, no flange

    If the Beck has a 1-inch back focus, there's something wrong with it, probably the wrong elements. It won't cover whole plate or even 4x5 like that.

    But you have some real gems with the other lenses!
