As for the BACKDROP SCENERY, I have it. Feel free to send me a PM, if you need it. It won't be expensive; but, it will have to be mounted. I think that I have 2 extra scenery placards, both of which need mounting.
Shay's repro backglass was essentially made for all models inasmuch as it had the replay window for the super and deluxe models, but it utilized the blue color palette of the regular/novelty version.
Tim, I'm glad to see your posted photo of the restoration progress. Looking good.
