[Lincolnville]

I’m trying to determine what versions of the ’32 Cabriolet rear window frames I have. The one closest to the rug came with the car and the outer trim is made of aluminum, while the inner ring is made of brass and held together by machine screws. 1st & 2nd pictures
I purchased the second one separately from the car, the purchase included the complete top – top irons, b pillar, top bow, header, etc. However, it is smaller than the original, and it appears to be made of stainless steel, held together by machine screws. 3rd & 4th pictures.
Since most of the car appears to be “early” I believe the first one is the early version as well and the second one is the third version?
