Some things we had back in the 60's when I started.
Timmons Splints. Made of canvas and had wood slats inside. They had rawhide cords attached and had eyelets on both sides, laced up like a boot. I believe these were military surplus.
First Aid Box. We used old resuscitator boxes, Tube Caddies, and even roller skate boxes. Seen some Knickerbocker bags back then (like an old fashioned doctors bag) We did not have that kind of money.
Thomas half ring traction splint with stockinette.
Heavy cumbersome O2 tank (Steel) With regulator with glass clock covers that broke the first time it was dropped.
If you were lucky, a Stephenson resuscitator with venturi suction.
A Motorola 2 way radio with a dynamotor power supply. ( you had to key the mike and wait a couple seconds before you spoke, as the motor had to come up to speed and supply sufficient plate voltage to the transmitter to allow it to work)
I know I've forgot a few things, I'm not the only dinosaur here,
Help me out guys.
