Fellas, I want to take the time and thank you all for helping me learn so much more about relays.  It never ceases to amaze me how much grey matter is out there within our ham radio fraternity willing to help.  I know we all feel that this 'hobby' of ours crosses all professional, religious, and political boundaries world wide in the pursuit of enjoying all its rewarding facets and sharing it.  For me, a very important portion of my journey on this earth of ours.

As a knowledgeable listmember replied, this could be a 110VDC coil. It 
could also be a "plate relay," used in the plate circuit/load of a relay 
control tube (these were typically 10Kohms nominal resistance). Even if 
not intended for use in that application, it certainly would work there.

73 and Happy Fourth,
