F-flute rosewood: who can help me with maker's name?

Me, and a friend who is the owner, like to know who made a keyless F-flute (rosewood).
It has an “S” in a heart and a number (1319) carved on the back.
The only info we have is that the flute was bought/made in the U.S.
I have recorded a few tunes with this flute, maybe somebody recognizes the sound?

Thanks!

Could it be a Ralph Sweet flute?

BTW, I like your “beats” recordings. Great fun to play with.

Sounds like a Sweet to me. The second clip down in my signature has a video of a Sweet in cherry, I like mine very much !

That’s what it is. I have a great one in blackwood. They’re a blast to play.

Hello Flute friends,

Thanks for helping !

Indeed a Sweet.

Cheers, and keep playing!
