About six months ago i bought a graflex series d. Overall it works well, but when put it on T and try to attempt a time exposure, the curtain sticks and won't move upwards. giving me no picture on the back ground glass. If it does open, it moves awkwardly. Is there some kind of lubricant I can use to make it move more smoothly. If so where do I put the lubricant. On the track where there shutter is atttached?
thx,
