Yes it's, 6x6 made in Germany during war time (1939-1941).
Front cell focusing, this lens it's f/4.5 75mm Enna Ennatar (triplet), double exposure system, 4 speeds, 200, 100, 50, 20 and B (fast speeds are halved but stable so pretty good to go), focusing with the original ground glass should be hard, very dim, but someone before me installed a new focus screen with middle split image so it's very quick as it's. I haven't dismounted since everything works fine, only lens cleaning.
Some photos at f/5.6 or f/4.5 will show vignetting.
I thought I already posted but here it's again

Very fun camera, despite after aperture is pretty dark, framing through the sports finder is very accurate. First focus as SLR with WLF, second shoot as normal SLR.
