We saw one!
There was a restored E-35-2 at the June rendezvous, and we were so smitten that we must have spent an hour aboard just admiring the workmanship. I do not remember the panel, per se, but since everything else was so nice, I bet it was also.
Perhaps some other owners can chime in with photos or links to other threads here. I know that, over the years, there have been some good electrical renovations reported on this site.
Best,
Loren
