Whos tuner brake?

[Link]

I have a tuner brake, the barrel is 3/4 od turned .500 inches back with a thread that measures 12 threads in .440'' with no thread for .060 at the shoulder. The muzzle end of the barrel is .910 where the turndown starts.. I would like to do away with the brake and just put a tuner on. [at the request of the neighbors. ]
I don't remember who made the tuner brake. What to do?
Im no machinist so the measurements might be a lil off. ;]

Take it or send to a smith, cut off the end and start over.
Go with "normal" threading.
They don't charge much for threading the muzzle.

If it's 3/4 you still need the number of Thread Per Inch TPI. 3/4 X ? to be able to find out who threads their tuner to that particular size.

EC Tuners have thread adapters that come in 1/2-28, 5/8-24, 3/4-24, and M18x1

So if its 13 threads in approximately .440 how many threads per inch would it be? There must be a standard. Maybe a machinist could help me out ? My math sucks. lol

Looks like it would be 24.

Looks like it would be 24.

I bet it would be closer to 28 if it is turned down to 1/2", but if it is only turned down to 5/8" then 24 would be standard.
