Hello,
I did not know that they did stop using their name on the hats they made. So I cannot answer that question. I believe that they may have made hats for other hat makers and millinery companies, much like Bollman and others did. Not sure at all. Now I think I have to find that out!
The style is a bit unusual, but it looks 1950's. That my guess anyway. Wondering why they used a thin rayon satin for the inside ribbon instead of the traditional grosgrain ribbon.
