Vintage Weaver Scope(s) Adjustments

I have acquired vintage Weaver scopes all with Post/crosshair reticles -
in models K1 - K2.5 - K3 & K4

I am having a hard time finding manuals for them. Trying to find out
what the MOA per click is on each model. Was told the K2.5 is 1/2 MOA.

Can anyone tell me the adjustment per click on these scopes.


Thank you
