The value of them seems to be about i got just over 400 usd of course mine sold for pounds,but they are fetching more as time goes on.Seems every time i see one on ebay it fetches more.Mine had rusty metalwork too.has yours got a serial no on the back of the peghead,i think mine ended with 64 or had 64 somewhere there.If yours has one you can date it.Lovely banjos in my opinion with agreat sound too.
