FWIW, it seems those numbers are seldom shared by the manufacturers, which is odd, since they can be measured, and makes one wonder what are they hiding?
I get asked for all kinds of info which I have learned the hard way to keep propriety. When a call or e-mail asks for specific measurements and technical data, 99% of the time it is simply an attempt to gain info to build their own.
I had one guy tell me because he could not afford to buy one ....I should e-mail him my CAD / DXF files so he could build his own. Best laugh I had that whole year.
