The lens is an 105mm f6.3 Novar-Anastigmat with Derval shutter, camera shoots 6x9 on 120 film. Camerapedia has 1938 for the same package with the Ikonta badging.

I just hope I can get results as good as those from mine! Obviously you have to guess the distance to subject and either carry a light meter or use Sunny 16, I'll be doing the latter as I can generally get close enough for negatives.
