I've recently acquired a Graflex 3a. In it's description it said that the shutter seemed to be working fine. Now that I've received the camera I've had a chance to play around with it and it seems the shutter is broken. I know nothing about these old SLRs. I thought it would be a cool camera to run (Ilford HP5) 122 film and 6x14 (120mm film) panoramas, but the mirror doesn't even go up. I've tried to do some reading about this camera online, but can't find anything that really helps. Does anyone have any experience repairing the camera or recommend a place that can get this beauty up and running again? The shutter appears to still be good, just not functioning well... or should I just return this to the seller since his description wasn't quite accurate?
