Maybe an O.T. but I'm in trouble with this hitch pin

anyone know where I can find the dimensions about the hitch pin in attachment ?
Is a Leica Geosystem standard I think.
I need to draw urgently the " female seat ", and I have only this pic.
Many thanks.

Try to find one piece from geometers and measure it. It fixed with sphere inside holder!

Here is a possible female part!

Yes, this is connector which is used in, I think "Leica Geosystems" for connecting equipment to tripods and similar!
