    anyone know this lens?

    Hi there!
    this is my first post here , and I have a question about this lens.
    Unfortunately there is no any sign on it. There are only 2 glass elements one on the front () and behind one )( about 180mm diameter. I think there are 2 elements missing, anyone can tell me what is it? thanks

    Looks like the front cell of a great whopping big telephoto lens...

    Ole, doesn't the classic tele have a cemented doublet in front?

    OP, it is the front cell of something. Could be a tessar type, could be a dialyte type. Both have a pair of singlets, () )( as you said.

    Probably isn't an episcope lens, those are typically mounted in sleeves with a focusing arrangement.

    If you're asking for advice, don't buy it unless you need a doorstop. As is it won't form an image.
