The #2 Brownie came out in 1901 and shot 6cm x 9cm, and all of the surviving Brownies I've seen shot rectangular formats. There was the Brownie 127 which shot square, but I only learned of its existence just now; have never seen one in the wild, probably because finding 127 film is functionally impossible.
