This bug is commonly called the Japanese Bug or Workman Bug and was sold by
several retailers.

Mine is in the original box. It is in like new condition.

The outside of the box says:

CALRAD
T.K. 12
SUPER SPEED TELEGRAPH KEY
SEMI-AUTOMATIC "BUG"

Precision built
Professional type
Semi-automatic 8 tension and speed adjustments.
Adjusts upward from10 wards per minute ( the "wards" is what it says on
the box!!)
Transparent dust cover

I think these are sometimes called coffin bugs, too. I can provide a
picture on request.

I've seen these go for $75, but I've never seen one with the original box.
So...I want $100 plus shipping.
