A friend of mine has an old one which is beat up and it needs to be replaced. I told him I would look out for one, and I think this may be the best way to find one. If anyone can help him out send me an email and I will get you in contact with him.
Glenn’s family MAY still have a few. His daughter Bree is still using his old e-mail address: Thnwzl@aol.com
Thanks Paul. Maybe they have a high D for him and a Low A for me. 
I have one and would be willing to let it go. Prefer swap for comparable value whistle to outright sale. Let’s talk.
