CPR produced some of the US denominations and I have a heap of these and some custom standard plastic windows.
I will have NOS Bally windows, and used Bally Windows. I will have used Williams in Aussie Denominations.
I also have the metal plates for 20c pieces. To the best of my knowledge, there will not be 50c or $1 plastic plates as the last of this type of coin door predates the $1 coin. I don't remember any 50 cent coin acceptors except the ones my Father custom made for Billiard and soccar table coin acceptors.
Whatever I can find, I'll send up.
