While cataloging wrenches for the Fall Wrenching News Auction I found this Bonney PWA tool. At first I thought it was a cartridge fuse but saw it was marked BONNEY PWA 1395 which is listed in Rusty's list as "PWA-1395 Drift, Fiber, Piston Pin, R-all,[Bonney]".
It's 6.5" inches long and the body is made of what seems to be some kind of phenolic with a metal cap. Doesn't look like it was ever used.
