Recently came across an Agfa Record I and ran a test roll through it - Works great, no light leaks... except the focus is stuck at around 8 feet. I was able to separate the lens from the shutter but the front two elements are completely stuck together. I did a search for cleaning tips and managed to get some of the old grease off with a little lighter fluid and cotton swabs, but still no luck. Didn't want to put them between any clamps or vices and risk having the metal get bent. Any ideas on how to get them separated would be appreciated.
