[Milsurplus] Parts

[telegrapher at att.net]

I' found a pack of what appears to be dynamotor brushes for the RDR equipment.  Whats that?  

I also found some tubes for the RDO receiver.  Need any original replacements?

I've also got a couple Crystal holder tins for the MAR.  Loads of xtals in there.

Got a cable, hope i didn't ask this before, that has an ARC 6964 on one end and an AN 3106-20-27S on the other.  The ARC connector looks like its for some command set application?  Looks commercially made so whats up?

Gotta thin out the collection here.  Lot's of stuff to move.
