[Johnson] Nye SSK-1-K Keyer

[Tony Martin W4FOA]

I'm looking for info (manual or copy of a manual would be great) on the SSK-1-K keyer.
Does anyone have one that could confirm that the supply voltage (external) for this is
12 VDS...also, it the center pin + ?
Thanks for any help...please reply direct with any tips.
