I don't know much about these, but to me other than the feathers being wrong on the eagle (a wartime fix????), it looks okay. The photos aren't of a very high quality and you may be 100% correct, but I've not yet seen a forger put a crack in the felt and there's one on this one near the front left visor. The problem for me is that I wouldn't know an original felt shako from a well aged fake, because the originals lack form, like an old felt hat.
Hell, I didn't even know that some had front visor trim until this week.
So there.
