[DISCLAIMER: this worked for me but the wire mentioned here is *rated* at 50V - which means it is only tested by the manufacturer to that voltage]

Most of the Philcos I've repaired have wire harnesses to connect to the speaker. Often these wires aren't in great shape (missing insulation, patched with electrical tape) so of course I replace them with new cloth-covered wire. That gets the job done, but it doesn't look exactly like the original harness.

As an example, the original wire harness colors on my 16B tombstone:

• white
  
• green
  
• green & white
  
• blue & white
  

With only solid colors to play with this means I have to add two additional colors to the 'look' of the back.

I searched far and wide to see what kind of reproduction striped wire might be out there and came across Rhode Island Wiring Service - a small company that caters to antique automobile restoration. They manufacturer a wide variety of wire styles - but most are heavier gauge than those used in antique radios. I decided to take the plunge and order 25' in the closest style for each of my 16B's original colors (the wire cost 0.25/ft.):

18BPW  18ga Braided Primary Wire BU-4W
18BPW  18ga Braided Primary Wire W
18BPW  18ga Braided Primary Wire GN
18BPW  18ga Braided Primary Wire GN-2W

Decoder ring:
BU-4W = blue wire, 4 white tracers - kind of looks like original blue/white pattern

I would have preferred GN-4W = green wire, 4 white tracers, but they were out of that so I had to settle for GN-2W.

Anyway, here's what arrived in the mail:

   

And a side-by-side comparison between the old and new wire:

   

I created a new wire harness by measuring out 36" of each color and twisting them together. I then tied each end with a number of turns of brown thread bonded together with hot glue. Here's a comparison:

   

and the final result:
