Shoe mount Koni Omega Optical ("auxiliary") finder for 58-60mm wide angle lens. Originally sold for Koni Omega Rapid, or Rapid Omega. I bought it for my Horseman when using the 65mm wide angle, and it worked fine, but I subsequently bought a Horseman universal finder.

This finder should fit most any 6x7 format camera with a shoe mount and for which a 65mm wide angle lens is available. It may be close enough for use with a 90mm wide angle lens on 4x5 with some mental adjustment for the difference in aspect ratio (do your own calculations), Bright frame line. Nice shape, $75 plus shipping. Photo on request.
