Looks like the newer and final font type that PM used.

I'm no expert on flutes (I just bought one though) but I would start with the usual suspects that were made in Elkhart Indiana. Maybe start with Armstrong flutes and see if there are any visual similarities with the keywork and such.

Congrats on the flute purchase!

Windy, are you equating to the acoustical standing wave to alternating electrical current?

So impedance equals resistance?

It's natural to think that a large bore instrument will be free-blowing ( the B&H Imperial 1010 may an exception to that logic).

The mouth piece / reed combo probably has the most effect to the player on how the clarinet takes the air.

Do you know if the "pre-R13's" have a larger non poly bore? I think it's referred to as the "Master bore".

Pure hobbyist level for me. I purchased my first clarinet at a Goodwill store 20 years ago. It was a Pruefer Silver Throat and I still have it!

I like to discuss and collect clarinets. Mostly old ones but I do pay attention the latest offerings from Yamaha, Selmer, Buffet, etc.

 The Sir Nicholas Shackleton collection is pure excitement for me  I think he was considered an "amateur" clarinetist.

With that being "said", I enjoy discussing musical theory, interval training, composers, etc., but when the day is done, I just like to make music with the best woodwind known to humankind.

Lately, I have been musically stuck in the Baroque period. In fact, I often wonder if our resident clarinet maker (Jared) would be willing to 3d print me a nice copy of an instrument in the style of Johann Denner. Either in 415 or 430 (=A) Hz.

Keep up the innovative work Jared.

There's plenty of cheap junk tenors on ebay. Don't hack an early Bundy 1. Those are essentially Buescher 30a's and are awesome and still cheap tenors.

I just posted a link to that in another thread.  Isn't it amazing?  All I've managed is a few folk flutes and a keyless "tarogato".

Oops. Sorry Dibbs. It is amazing!

 With the right equipment, a bass just might be possible.

Sweet!   Those old Noblet cases are nice as well.

Should be a nice "horn".

So with the simple system clarinets having the 2 rings on the lower joint (added by Adolphe Sax 1840 ish?) . . . does anyone know how long these were in vogue until the additional 2 rings on the upper joint appeared?

I think the Albert's were advancing very quickly once Iwan Müller's design was established.
