Parker Hale PH5B usage question

Does anyone have a link to a users manual for the PH5B?

I would like to know:
a) how many MOA per click for elevation and windage?
b) On the front of the sight, there is a knob that can be pulled out to slide the sight up/down in large elevation increments. How many MOA per increment?

Thanks.

Curmudgeon, you need
HARC-MCRRS Home Page
scroll down the index on the right edge of the home page and you will find an entry for "Parker-Hale service rifle sights".
