Victor concert junior Long throat - how to open

[kropton]

I am asking for advice on how to open the housing and is it possible not to damage the diaphragm?
Pictures would be welcome

Someone else will post who actually took one apart, but logically the only way it looks to come apart is the outer knurled ring unscrews from the body.

[kropton]

unfortunately not, both parts are pressed together and the only option is to knock the pin out of the knurled body. but perhaps someone has some ways of another method.

What pin?

I use a translator, I meant that one part is connected to the other by pressing

[JeffR1]

How do you know it's pressed together ?

Pointed out what looks like the beginning of a thread.
I'll stick to my threaded theory until proven otherwise.

They're pressed. This will not be the first time someone has taken one apart.

I see. Thank you sir!

I planned to use a puller, but it will break a good, original diaphragm.

or the second method is this tool
