    Description

    Cool find.  Massive 5 3/8" diameter.  Heavy case with thread mount.  Has BF FF markings and a serial number which makes me think military or scientific.
    Has dust inside and a very small chip on the front.
    Great to collect or turn into a new scope of some kind.
    Info from a helpful ebayer:
    Just FYI, the BF and FF are back focus/front focus lengths. So this is probably around 20” focal length and f4.  That really fast for such a long lens. May be good for wetplate collodion photography. Need fast lenses for portraits there.
