So I picked this up at our local antique fair in Long Beach CA, it was so unique I just had to get it. This is apparently made by Frederick Gosparlin hence the stamp and Pat ??? as shown in the photos. Frederick Gosparlin was a master violin maker and had many patents registered by him. Obviously this is a custom and possibly a one of a kind, it is just a fine piece. This might be for sale later as soon as I find more infor so any help is much appreciated. I have included many photos for your viewing enjoyment. Thanks Steve
