[Milsurplus] Jones Plugs

[Lloyd Godsey]

Might not have been Jones early on, might have been Cinch. the Beechcraft 
D-17 used one to plug in their master electrical switch box. A BIG honking 
one. Had 2 alignment pins if I recall, however I could be wrong. I still 
have 1 or 2 in storage.
How do I know? I fabricated 3 master electrical boxes for a friend of mine 
who is restoring a D-17 and has 2 more in storage. Lucky dog. His Dad bought 
them back in the late '40s when nobody wanted them.
Thanx
