I recently purchased a nice older Stetson Open Road with a wind trolley. The trolley is too long though and flops around on the hat. After looking at it closely the back of the button looks like it snaps into place. I gently tried to open it but didn't get any movement so I stopped. I don't want to do anything to damage the hat because I can live with it like it is but if I could unsnap the back of the button and tighten the cord that would be great. Has anybody tried this? Does anybody know if the back of the button unsnaps or is glued in there? Thanks for your help.
