Neighbours windows might be a clue? I'm obviously a bit of a window geek so I'm trying to tie the architecture to the original window style. At a guess they were 4 per window because of the date of construction and larger glass sheets were a more specialised item. I'm always happy to find exceptions though.

No idea on the original. It was gross PVC when I bought it.
