Dinerman said:I've had borsalinos with cavanagh edges.
I had one with a double cavanagh welt, with a seamless welt on top of and on the bottom of the brim. Paper thin felt on that one, no pictures at the moment. Only hat I've ever seen with that treatment.
Dreispitz said:Were the felts actually produced in Europe by Borsalino or rather sourced from a US manufacturer for sale in Europe?
Dreispitz said:Was it a parallel development?
If so, did it gain market weight in Europe?
The process was protected by patents in the USA. How could Borsalino sell such hats in the USA without some licence agreement with Cavanagh? Is there some material?
carouselvic said:When I posted those photos I thought you were after European manufacturers who made a Cavanagh edge. If I understand you correctly now, you wanted hats made for the European market? My Borsalino has a oval that was a registered trade mark, it has nothing to do with the Cavanagh edge.
Dreispitz said:If I recognise it properly, there is a patent number printed on the lining. I put the hat post 1930.
