Cox made red plastic backplates/mounts for the needle valve and reed assemblies for the Pee Wee for use with separate tanks, but I've never owned or flow a product Pitts or Ryan so I don't know what they were like inside. Nice looking unit, too. I love to have at least one for use with my Pee Wees.

What did the backplate look like that was used on the Little Stinker U/C biplane circa 1960?
