The lens which came with this camera https://www.largeformatphotography.i...66#post1498266 is unmarked. Focal length is something in the region of perhaps 15~18 inches (no ground glass to check better). Both front at real elements are about 3" in diameter and it has a rack and pinion focus but no aperture control. The shrapnel damage and separation (should align but I don't want to force the slightly distorted thread) are visible. It appears to be two groups and as far as I can tell both are doublets (I can't extract the rear group as yet to fully check). There is no aperture control, no slot and all I can think is that this was fixed on the front although the damaged section has no thread. Any information or suggestions welcome.
