Recently I acquired a little Zeiss Ikon Box Tengor from a fellow shutterbug in the UK. It's one of the early models with controls similar to the Model F box Brownie. It came together with a portrait lens and a crusty carrrying case. All for the price of shipping it to 'Dutchie Land'. Inspection showed that it had a little surface rust here and there, but the rollers were clean and the lens was in nice condition too. Doing a little research I learned that the f-stops are supposidly f/11, f/16 and f/22 respectively, though I doubt this. I guessed the shutterspeed to be about 1/30th of a second. Having learned from previous experiences with the Box Brownie, I loaded it up with 400 ISO Kodak BW400CN and waited for an opportunity to shoot with it. I guess the exposures were okay with a little bit of camera shake here and there; but the biggest negative, pardon the pun was that somethings really scrathed the negatives in a bad way, all along the length of the film. I'd love to blame this on the 1-hour photo guys, but I fear this cute box camera's to blame. Veterans at the Capelsch Veer Memorial two weeks ago (The willow in the background was the last tree standing after 30 days of fighting in the winter of 1944/1945) 7th Armored Tank Destroyer re-enactors with a 'captured toy' during the "Footsteps" march in the Ardennes last weekend. So I inspected the insides of the camera and found a few probable causes, there's two little lips of metaal sticking up in front of the rollers, but I doubt these would touch the film when it's wound tight as usual. The rollers themselves might freeze up when film tension is too high. doubtful. There's two other metal lips along the short edges of the focal plane, I suspect the backing plate pushes the film up against them too tightly causing the scratches....hmm what too do... Sand them down a bit, removing any rust and sharp edges there might be on there? Somehow lower the pressure of the backing plate?
