I'll post additional pics.  The tip isn't good.

wow that proto screwdriver is awesome, Im jealous! 

This week's estate sale buy had some interesting woodworking tools, including a Disston D8 rip saw, a Disston D4 backsaw, and an Atkins No. 25 dovetail saw, an egg beater drill, and a  nice wood rasp. Bonus buys include a really long Proto wood handle screwdriver, Seymour Smith anvil pruners, Fuller 2.5 inch deep C clamps and an as yet unidentified ratcheting Phillips screwdriver with a wood handle

You sure did.  I thought you were pulling my leg at first.  Thank you very much.

Taxidermyman . I think you nailed it!

Looking for info on what these could have belonged to. The male thread is 1/2-13 , the knob is approx 1-1/2" in diameter . The knob has a brass insert with a 3/8-24 female thread .

Im pretty sure this is used to show how pascals law works in a school experiment, I found one at UofT once

Estate sale garage find that came with an assortment of other tools.  No markings at all.  Chrome plated about 14" long.  The chrome ball at the end is about three inches across and covered with removable nozzles or sprayheads.  Can't get the handle assembly disassembled but it appears to be a plunger assembly that you push to distribute the contents inside the ball assembly through the nozzles.  Would have to be an extremely fine powder or liquid to be able to push it through the nozzles.  Anyone have any ideas what this is.  Thanks in advance.

Here is my Mephisto auger bit.
