  1. Re: Klay's Multiplying Plate Holder - rare back

    It's amazing what still shows up after all these years. It looks to be in nice shape, too. Have fun.

    Re: congo 300mm f6.3 can you tell me more

    Lynn, thanks for letting us know the derivation of "Congo". I had wondered, but although I had the pleasure of meeting Mr. Yamasaki years ago, I never thought to ask about it.

    Before the Apo Lanthar, apochromatic lenses for photographic work were mostly barrel-mounted lenses with apertures of maybe f9. The idea of an f4.5 apochromat in shutter for general photography was...

    Re: Calumet CC400: A few questions.

    You are perhaps better off that a lens wasn't included. I have seen many of these sold with a lens lacking the excess coverage needed to use the movements which the CC400 has.

    Re: Brass from where? & Shutter ID plz

    Your shutter has an actuating cylinder for each mode. One is a more or less "Instantaneous" operation, the other a "Bulb" or "Time" function depending on how you work the bulb.

    Re: Help! What is this camera!

    Yes, Blair was absorbed (one of the many) by EKC in 1899, but the Blair name was used for some years longer. Hawk-Eye was once a Boston Camera Co. name, but Blair bought them in 1890.

    We need excess coverage in order to use movements. Your lens probably would not allow using rise on 11" X 14", but would on 8" X 10".

    It seems appropriate to mention that the "size" numbers mean different dimensions for different makers. An Ilex #5 is not the same as a Wollensak #5 and both are smaller than a #5 made by Deckel.
