I am pasting over the contents of some PM exchanges for other peoples benefit.
Here's the latest:
Well, the key was I had a torn bellows so I was able to get some access from the front (maybe removing the bellows first on your camera would give you access). I also used a needle nosed pliers to loosen one wood screw I could not reach with the screw driver.Originally Posted by B&Jdude
I took off the top tensioning lever first, then the screws for the top plate and then the screws at the bottom of the shaft. I then had to take off the rear lens hood. After some wiggling the bottom plate and the top plate came out. Pretty straight forward. The shaft and lens are dangling from the leather.
I did not remove the front 10 screws. I tried months age but stopped when it became difficult to get all of them out. Now I have more incentive; I need to find a piece of leather to replace the bellows.
