At a buck a book, how could I refuse?
The untitled one is "Machine Shop Operations" , American Technical Society.
There was a 7 volume welding series and an OA welding book I may go back for. Lots of old cast iron small mechanical stuff and some interesting odds n ends.
Picked up a nice wood pantograph dated 1946 for 2 dollars. Started raining so I couldn't look at everything really good today.
