I have aqiured an elderly lens, hoping to find some use for it on my equally elderly German "Reisekamera".

The lens is in a Regno shutter (which is slow, but works). There's a triple aperture scale for "10 1/2 EQ.", "18 BK" and "23 1/2 FT" which I take to be combined, rear and front element respectively. The aperture scales are the old US system running 8, 16, 32, 64 etc. I believe the 16 corresponds to f:16?

Counting the reflections I find four surfaces to each half, which confuses me a little...

Does anyone know anything more about this lens? Anastigmat or Rectilinear? Approximate age? Coverage?

Thanks.
