[Boatanchors] "Keying" relay

[WØQFC]

Years ago I remember a small relay that had a plastic cover. It was about 2" 
x 3" x 1" high.
I think that it was called a keying relay; well guys & gals, I need one! One 
if it is s.p.d.t. or d.p.s.t. and two if it is s.p.s.t.
12v dc preferred, but any voltage ok.
Anything out there for sale or trade?
