I have had the 2 Garvey panels for years. They are damn tough and when they do pop up, sell for good money most of the time.
Turns out the 2 variations I have are two different years, but I didn't realize it at the time.

I have at least 1, maybe 2 more panels (I believe I have the Carew/Henderson shown as well) and 4-5 single discs.
