so I bougth an agfa super silette (1955, compur f3.5) today, with the only caveat by the seller being a stuck shutter cocking mechanism, but after buying it i discovered that the shutter speed dial was extremly stiff not being be rotated to the far end of either side(it can only rotate from 60 to 8 ) and even doing that creates an unpleasant mechanical whirring, and sometimes discharging the shutter - otherwise the focus is buttery smooth and even the delayed exposure mode works, the only ther issue i noticed is play in the whole housing. Is there some setting i overlooked to turn it freely or some special way to service way.
