At an old house on Lake St Clair I found this 50's Senco air stapler and 30,000 staples for about $2.
I could not test it but I figured it is so simple I would give it a try.
It looks like the beginnings of the pneumatic revolution was rather simple.
Found lots of patent drawings to help get it back together after an almost complete tear down.
The thing works really well but does not have a pressure adjuster on it so you have to have an air regulator on the line.
