1930s Woody Glass Window Hardware

[jea777]

Does anyone know of parts or info on the window riser mechanism and metal cover plate used on the 1930s woodies?
I know that the Model A and maybe Model B woodies used curtains, and the 1937 had glass roll-up windows. I do not know what year Henry started using glass.
Do they interchange with any other bodies?
I would like to purchase a pair of assemblies.
