Joe Filisko 1313 Colorado Ave. Joliet, Illinois 60435-3704 (815) 725-9095 Mr. Filisko is a very busy guy. I have no idea whether he's taking on any new clients at this time. He's very nice on the phone and very willing to share information. Mad cat's harmonicas are Filisko round hole bodies with Huang plates. The plates are set-up by Joe. FJM
