B&L stand for AO StereoZoom ?

Hi,
In my quest for a little AO stand, I found only a KT stand at 200$ : too expensive for me.
I see a photo on the webpage http://www.usedmicroscopes.com/ of an AO pod on a B&L A stand.
It is not expensive to buy and not hard to find a B&L A stand :
Someone can say me if an AO 569 pod fit well in a B&L A stand ?
Can someone send me the internal dimensions of a B&L A stand ?

I didn't find any B&L Stereozoom manual on the web : do you know a website ?
