[GreenKeys] Early early Model 28 catalog - many prototypes

[Duncan Brown]

Interesting reading, Nick!

The "Immersion Proof" cover probably came from the US Army's requirement 
for the TT-4 to have one. The TT-4 would supposedly float when packed in 
its immersion-proof cover.

Section VIII (p 51),   A. Keyboard Perforator - Nontyping. We have one 
at the AWA Museum. It has a neat "vacuum cleaner" powered by the motor 
to suck the chad away. Looks like a squashed (not as tall) M28 KSR, but 
the label on the back says "Model 34/35" . (I guess a "M34" was a M28 in 
the M35 line?)

Have fun
