It's a 32 page pamphlet, in good condition. "Revised 10-46", but does not
appear to have a proper copyright. I found it recently at a used book store.
I don't see it online anywhere. I am willing to scan it and/or send the
physical copy to someone who needs it. $5 plus shipping to a private
collector, free to a museum; museums (e.g. bitsavers) get dibs.
