I recently purchased a Wollensak Raptar LE [2] 10" 254mm f4.5 lens in barrel. On spec I got the lens in the hope that the elements would fit my Alphax #4 shutter -- which they do.

The lens is not a tele raptar, it focusses on infinity at the 10" mark and covers 5x4 no problems but I cannot find any meaningful information on this size lens. It is from what I can determine a Tessar design but the LE [2] designation is the curiosity.
