So it could be some kind of non-specific Stetson that is kind of Open Roadish/Stratolinerish?Well, we have divided opinions on whether or not it 'counts' if it doesn't say Open Road. I tend to be in the 'has to say it' camp, but at the same time my Stetson 100 doesn't say Open Road anywhere, but the tag does. So you see the issue.
My initial impression on this one is not an OR. Mainly because the brim is at 2.5". I can't swear that there was never a 2.5" brim, but the OR is usually 2.75". The flange looks a bit deeper too.
