They are harder to find than normal cockades and were made 1930/1940's approx to fit the caps made by the firm robert lubstein. He had a patent on a fresh air system that allowed the outside air to come inside the cap via thye cockade. Helps to Stop that red mark you get on your forehead when you take a hat off.
What you need is someone with a vented erel cap without the correct cockade and sell it to them if you want to max your $.
Or if you are very generous give it to me and I would be a very happy said person !
hope that helps
There is every chance for that arty ! I reckon with some tlc you can put that back to it's former glory !!
Give it a couple of days work and the Erel will be back. Post me some pics of the inside and I can talk you through what can be done to save it.
ps you should send Julekpl the cockade for his hat.
I must report that this Erel is no longer in my possession...I have been offered a nice amount of money for it. I sold it 3 days ago :') but it has a good home.
