Old American tool

[Gerry]

I was going to put this in the tools section but found I cant start a new topic there for some reason.
Anyway this is an old style tool for lapping bores or holes to a fine tolerance. You put a fine grinding paste on the brass bit and then using a drill turn the bar working it forwards and backwards. On the end is a thread which when wound in will expand the brass bush. So you can lap a hole to very fine sizes. Kinda long winded but very cool. Whats more its MADE IN THE USA

Stamping on the shank says

Where I used to work we had something like that only it had blade where the grooves are for reaming bushings on big trucks.Pretty cool tool.

That will be an adjustable reamer. I use on of those to do my king pin bushes.

Something on that order would be great for both king pin bosses and the spindle bushings, yes? this is a one size only tool?
