Hi,
I just came across a Turner Reich convertible. I am unsure what the combined focal length is. The front element is 24" and the rear is 18" It has an F/stop scale for 5 different lengths, 13" 11" with a little 2 above it, 10" with a little 2 above it, 9 with a little 2 above it and 8". I have been told by a colleague that the combined element length is 300mm and that it would cover 7x17, but I am not sure that is correct. It is mounted in an Ilex #4 Universal which seems to be working reasonably well . There is a tiny bit of separation on the front element of about 1/2 mm around the perimeter. Can someone please let me know what I have here, how much it will cover, what the image quality is and what it is worth. Thanks in advance.

The focal length when both cells are used is 10 1/2". This is the "No.4" combination which was suggested for use with the "Whole Plate" (6 1/2" X 8 1/2") format.



Your best bet in finding out what the image quality is is to try it.
