Hi All, I have 24 wooden violin pipes that were made for PPCo back in the 1980s. They have never been used. The caps have only been glued to the first four (A-C) and last six (E-A) pipes. Here is the information I have about the set and a picture of the actual pipes. http://www.johnatuttle.com/pipes.html Any reasonable offer will be considered.
