Definitely one of my better purchases, I never expected to own a bomb arming switchbox in such great condition like this.
This is one of the more complete examples too, with dial selector and jettison clip (5D/1060).

Whenever I get something like this I like to provide some basic specs just in case anyone needs them, so here's some details:

Width: 6.5in (box only)
Height: 3.75in (box only)
Depth: 2.0in (box only)
Weight: 2.75lb (total)
Rear mounting holes: 5.85in (width) x 3.1in (height) x 1/8in (dia.)
