Conn 50H valve/attachment bore size

I'm working on another frankenhorn project, and as I'm exploring parts possibilities, I have a question about the Conn 50H.
What is the bore size of the valve on a 50H? Is it .562" like an 88H, or is it smaller--perhaps .547" or .522"?
If anyone has a 50H, and a set of calipers, some measurements would be much appreciated!

Great--thanks!
One more question: are the oversleeves on the hand slide soldered on, or are they one piece, drawn into the tube itself? I can see from pictures online that the oversleeves are yellow brass like the outer slide tube, but I'm not 100% on which style of construction it is.

50Hs are drawn in, 79Hs are soldered on nickel

Got it--thanks!
From the pictures I've seen, they look like soldered-on brass tubes, but I couldn't tell for sure.
