Model a Coupe Roll up rear window

[Harpkatt]

Good Morning! I saw a video recently of a Model A Coupe with a Roll up/down rear window. I have never seen this before in one of these cars or maybe just never noticed. I dug into it a bit and found a few more examples, not a lot mention of them online, but some. Are these all aftermarket conversions? Did any A's come with roll up windows in the rear? This certainly would be a nice feature to have in mine. Not that I'll be cutting into mine to install it.
