Doyle Lane had a huge supply of pipe freins in all sizes that he
acquired with his purchase of Ralph Tussing's T.R.T. Manufacturing
Company inventory.  I don't know what has become of Doyle's stuff after
he died June 14, 2010, but someone reading here may be able to say.

I know freins are used on violin and other "string" pipes, but on
flutes?  Live and learn, but how much time do I have?!
