Antique 1930s Harvard sports wear corduroy hunters outdoor trappers workwear chore brown sale hat size small 60cm

Incredible hat here, by 'Harvard sports headwear'.

Bit of a guessing game with age but im saying OLD - probably not past the 50s certainly, but I actually think much older - materials feel it, the stamping inside and style...I think this is bordering antique kind of 20s-30s hunting hat.

Some unique styling to it - on the back is a slit/ pouch to store sale things. Bit like a gamers pouch - would one keep a couple of shells in there prehaps ? who knows but very unique never seen this on a hat before. Inside is thick cotton lined, there are a few small holes ive shown last picture but the rest looks good.

Measures
60cm inside circumference ( fits like a mens Small)
