Cool old rotary file catalog
 

I was going through some of my stuff and I came across a 1957 Nicholson rotary file catalog (what plugbuilders refer to as ball rasps).
This belonged to my father in law who restored antique cars and had about 1 of every tool ever made.

I love the rocket ship on the cover. A great example of American manufacturing.

I would love to have a set of the rotary burrs (rasps) 1/4, 3/8, 1/2, 3/4, and 1"
