[ARC5] ARC R-19 receiver

[Glenn Little WB4UIV]

At a local hamfest I bought a R-19 28 Volt receiver.
It is less dynamotor.
I think that this is a type 12 receiver, specifically a R-508.
I have been unable to find any thing meaningful on the web for this 
receiver.
Can any one point me to some documentation so that I can get this playing?
I would like to find the connectors to fit the radio.
If I cannot find them, I may be able to make some connector sockets and 
epoxy work.
Is there a connector to fit the dynamotor connector?

Thanks for any help.
