Identifying old whistles

OK , now to look inside.

What do you see ??

First gotta know parts…paaaaartition, say it outloud, paaaaaarttiton…well it is pretty plain, really just parts the two sides ( unless it is REALLY old, then there is none )

Perhaps it is cast and that helps to know.

Now perpenducular to that is the disc. Cast ? Machined ?? How is the disc attached to the paaaaaartition ??

This part is IMPORTANT !!!! — LOTS of notes to put on your tags, in your files – somewhere.

Then there are those pesky tines…pointing towareds the mouthpiece or away towards the top ??

What shapes are they ?? – very IMPORTANT once again !!!!

Record, record, record,,,

Do drawings if necessary….
