Getting to the end of a 25 year project and I have an interesting challenge for my 1923 Dodge screen side. There were no side curtains with it when I pulled it from the barn. It has various snaps and fastners which I have but there is one I can not identify. On the bottem of the side curtain and in various other locations it has the following fastiner which I am unfamilar with. It is neither lift a dot or murphy, what is it and where would I get the female part.
