I bought this Borsalino hat yesterday. It has the wind cord but is missing the button. I read a thread that dates the hats by the first two digits under the sweatband. The only number I see is 1177 and this hat surely isn't from 1911. I would guess mid 50's? The store it came from was open 1907-1981. It appears to be in pretty good shape other than the liner being faded and the sweatband being a little worn. The paper says bismuto nera which I assume means the color is bismuth and black.
