Question on vintage...

[TomS]

Hi Folks:
I'm curious to know what the hive thinks about the age of this hat? I've done some reading here, and I'm guessing late 1950's? Also, would anyone be able to make a guess as to what the stamping on the inside of the sweatband, shown in the last pic, indicates?
Thanks in advance,
TomS
