I very respectfully disagree about the 52 or Columbia block, Ole. I own both 52 blocks and blocks marked Columbia. The Columbia blocks are the straightest sided and flattest topped blocks I have ever seen, even more so than the 52's. I have handled a good amount of 20's/30's European hats and for the most part, the block profiles were not flat on top, they were more rounded. I am not saying that there were no European hats made with 52 and Columbia blocks, but from my experience, the straighter sided and flatter topped block profiles were an American thing. Even out of all the 20's/30's American hats I have owned, many of them used rounded topped block profiles. They were tall, but more round.
