I saw this O_ER camera and purchased it because it is a primitive metal box camera similar to the ones I build as a hobby (see my other thread here) https://app.box.com/s/xrbusg337r0z7anx886r https://app.box.com/s/4qqycmklzpot42bzz7h4 https://app.box.com/s/f4vrui54o9egyjwe2xir The O_ER camera is very solidly built of machined aluminum, the box is of folded and welded Al plate. and has the Ilex #3 shutter with the Oscillo-Paragon 1:0.85X ILEX 3 Inch (75mm) f/1.9 and the back is a heavily built Polaroid with no apparent model number , serial C8403750. The purchase price was a fraction of some prices I saw for just the Oscillo-Paragon lenses. The camera is in good condition, the lens appears clean except for dirt on the front glass. The shutter works except it does not latch on B & T, and I have not timed it yet. The shutter is the "press" type and works with a cable too. The distance from the centre of the shutter to the film plane is about 150mm; I don't know where the N2 is yet. I don't think this is an ordinary oscilloscope camera (I used many in the day) and I assume it may have been a process camera for copy work. I would be interested to hear if anybody knows about this camera. I see some negative reports about this lens used as a normal camera, but I will go ahead with a modification anyway. I am getting good prints up to 17 inch (430mm) from my other medium format cameras and my home C41. Here is my plan to modify it (I have enough machining and measuring equipment to do it, I think) Don't hold me to it, am busy, not fully retired yet, , it might take me a year or two! 1. Clean the lens and shutter 2. Check calibration of the shutter timing. 3. Cut the box length back to infinity focus for the lens 4. Make a back for the Graflex RH/10 ( I have done that before) 5. Modify the unusual but solid lens external structure for focussing and limited tilt movement. 6. Escape route: if the lens is no good for general work, I can replace it with a better lens. Any comments will be appreciated.
