One of my interests is collecting and repairing whistlers and similar
whistling items.  I can answer most of your questions but it may be
quite lengthy so I advise you to e-mail me and I'll give you my phone
number.

Robbie, the Wendels are making a small variety of whistlers using most
of the Griesbaum tooling.
