Hello,
I tried to contact Ronaldo Reyburn by e mail, but I did not received any answer. Do you have news from him ? He might be very busy.
Anyway my question was about the delay for a low D whistle, and the suitest bore to play in session (I mean wide bore or narrow bore ?).
If you have any information to give to a lonesome whistler …
Cheers ! 
Well, he just posted this:
He’s around. 
I’ve never played his narrow-bore but the wide bore is fabulous.
Doc
Hi there Birl,
I have not received an email from you and my system seems to be working ok. If you are looking for the sweetest tone for your sessions, I recommend the standard bore model, which is the narrowest of the two I offer, (also the fastest response) and the wait at this time is 3 to 4 weeks.
A back up email address is reyburnwhistles@hotmail.com
Take care
Ronaldo
thank you for your replie ! (good to hear from you 
)
see you on e mail !
cheers
