Early 50's Mopar rag top rear windows, glass vs plastic

[Ron42Dodge]

So I have seen both the full plastic rear windows and I have seen the 8" x 30" Chrome frame style on 1950 - 1954 Mopars.

But what I would like to know, which one was the standard and which one was the option or how did that work?

The 40's Mopars mostly had the chrome frame because the full plastic windows were not yet available. So it would seem logical that the New inovation (the larger plastic window) would be an option. But I don't really know.

Does anybody have a knowledge on this?

It seems that this desicion would need to be done at the factory.

Reviewing owners manuals, it appears the large plastic window began in 1949. That's the first year I see reference to "care of plastic window". This was also a major body change, so that makes since.
