[Milsurplus] Dynamotor brushes

[telegrapher at att.net]

I found a couple of packages of "Brush Assembly, H.V. & M.V. for 
Dynamotor PE-98F.  2 Brushes in each sealed package.

Also a couple of packets of brushes for the RDR.  Symbol on the package 
is U-801-C & D.  These are brush and spring assemblies.  COuple of 
packages of them also.

I then have a little black cloth holder that holds 8 brushes.  2 of a 
large size with marking of CM 5N, 2 with a CM 3 and 4 with a marking of 
6/82.  These are smaller brushes.  Again no idea where they came from or 
what they are for.

Then in a wrapping of tissue like paper (brown) i have 6 more brushes 
marked as CM 5H, 4 marked as 6782 and a pair of smaller brushes with no 
markings.

Anyone identify any of these items?

Thanks
