horizontal milling machine

My small "Armor" horizontal milling machine manufactured in the late 1940's by the Aircraft Machinery Company of Burbank, CA.

This particular horizontal milling machine is not a usual specimen since there is no knee. Instead the entire spindle assembly moves up and down the column on a leadscrew. I am not sure if this is an improvement over the normal knee or not, but it does seem to have above average rigidity for a small mill. Perhaps this is typical of the horizontal variety in general, I don't have enough experience with small vertical milling machines to tell.

When I picked up the mill I also got a "manual" which is more marketing material then anything. I am attaching it here in case anyone else has one of these and finds it useful.

I have also found a bunch of links on the web that talk about the mill.

This was a fun one. I saw a listing on craigslist for a small horizontal milling machine. It was about two hours south of Seattle in a little town called Castle Rock. The photos looked pretty cool, and it had a shop made vertical head and a bunch of tooling. I had never used a horizontal mill, but after some very brief research I decided I wanted it. The price seemed reasonable, but what did I know.
