check eBay. I see there is a B&M 144 Owner's Manual.... supercharger manual. also covers Weiand and Holley
Maintaining Gear Lube Levels For Weiand and Other Superchargers
The blower lubricant level should be approximately halfway in the front sight glass or between the marks for dipstick equipped units. If additional lubricant is required, add 80W-90 or 85-140W gear oil meeting GL-5 specifications through the brass plug on top of the front cover. Do not use synthetic gear oils in these units because the seals are not compatible with these lubes. The rear bearings are sealed and should require no attention for the life of the unit.

Got the owner's manual today. B&M recommended 5 fluid oz. 90W gear oil "or other good grade automatic transmission fluid" filled to bottom of drain hole on the front of the case. Change at about 2-3,000 mile intervals. The manual is intended for SBC installations, but the blower info itself is excellent. Thanks again Thirsty Thirty and Vincent.
