Yes, I know. You'll never find them... But, if I can convince one of you who are blessed with an original set to get an impression or simple mold of the exterior shape of each side. I am happy to pay for the effort.
Let the group know how it works out and how you attach them. Pictures of the project would be good for our group.
Thanks
After further thought and research, it seems Tony Berni can make very nice copies at a cost less than what I could fabricate here in California.
