Thanks, I´ll try the steam.mayserwegener said:Yes steam would probably help. Steam it up good and maybe it will conform to your head. You will not damage the brim. A cheap hat jack stretcher might help to get more of a oval shape.
The label doesn't reveal much which I was pretty much expecting. Doesn't look like the liner is sewn in so it might be even late 60s.
Late 60´s, or even later is what I was thinking. It has quite low crown and wider brim, like modern Tonak homburgs (which are surprisingly not listed anywhere on their website, but can be bought in their shop)
