I have a pretty Korona 5x7. The overall cosmetics are very good (no exaggeration); it has what appears to be a new bellows; and I have the rear extension track with a stamped number that matches the numbers stamped on other parts of the camera. I estimate that it is a fairly late model as it has front swings, tilts, shifts, and the hardware which secures the lensboard is the later type. As I mentioned, pretty nice and a pleasant camera to use.
When locked down, there is about 1mm of wobble at the top of the front frame; I'd prefer that the lash wasn't present but I can work around it. The rear frame must wobble about 4mm when the advance knobs are locked down; I find this excessive. I don't see any means to remove that lash from the mechanicals. The play seems to be in the guide slot on the side of the rack.
My present solution is to use a softwood wedge between the rear frame and the track to secure everything once I've found the working position for the rear frame. Not an elegant solution, but it does work and the wedges are pretty inexpensive.
My questions are:
Do other Gundlach owners face a similar problem?
If you have similar wobble in the rear frame how are you dealing with it?
Is there an adjustment or mechanical solution that I'm missing?
Thanks in advance; all comments are welcome.
