I bought some fixtures at an auction at Masterman Engineering in Kent
WA.

The ones with the tapered holes match the taper description in
"Machinery's Handbook" for R40 and R50 tapers.
The cylinders are 4.464" in diameter and 2.79" high.
This hardware is precision ground.

What are they for?
Could I sell this stuff on Ebay?
I don't think I will ever graduate from R8  taper.
