Guest above said all I was going to say about Windsor Banjos.
I currently have one from 1926 and have changed the velum several times. It plays fine using a variety of styles and stands up well to my more modern instruments.. I do own a 5+ 1 which I made by converting the nut and tail piece of an Emile Grimshaw circa 1935. Currently in bits awaiting a new velum although the old one has the makers signature on it so worth keeping.
