I have a chance to buy a Columbia AB (MacDonald) Graphophone in excellent condition. It does not have the large slip on Mandrel to play the Concert Cylinders, but everything else is there, and cabinet is in beautiful shape, and it is in running condition. Serial Number is early in the run 752110. There is a strange little 10" by 4" wide black horn that comes with it which I think is probably off market. What sort of price would you estimate this AB (MacDonald) would be fair?? I looked on ebay and none have sold in the past month or so.
Thanks in advance, Bruce
