Purchased at a semiconductor company liquidation last year, and it is brand new..  We removed it from the plastic covering to take pictures.  We don't know much about it, as it was made by people who apparently couldn't write, so they drew little squiggly pictures on the label (see Picture #8).
According to the yardstick & calipers

Overall length:  19"
Port inside diameter:  3.927" / 99.76 MM
Flange outside diameter:  6.5"
Flange bolt pattern (approx.):  145 MM (center to center)
