Sounds like Brantoken. Vacuum 'stilling is a pretty small club.
Distilling at 120f and 100 torr.

Yeah, thanks, AE. I appreciate your interest. I'm afraid I am the old mechanic of reference. The first vacuum gauge I connected to my still was the same one I used back in the day to adjust carburetors
and diagnose sticky valves. I'm so old I remember when engine vacuum was used to run the windshield wipers (a terrible idea, BTW. Worked fine going downhill.) In those times manifold vacuum was decreed by God himself to be 21 inHg at idle, and crankcase pressure was regulated by a breather cap in the valve cover and an open hole in the side of the block with an upside down U-pipe stuck in it to keep the oil from running out. And visibility in L.A. was about a block.
