winston... I edited the photo to have a pixel size of about 500 x 800 pixels. That keeps it on the screen at a nice size.

Thanks for posting your restoration, great reading. Good job on tracking down and fixing the problem!!!
Cheers,
Bob

Good job Winston! One minor mistake - now you know. Glad you found it. Thanks for the advice on repairing he padders Ron! I hadn't found the online "mica store" yet, so I wasn't sure what to do for those.
