Wireless Set No. 52 Canadian - Project

[David Dunlop]

Hello Chris.

I was looking for signs of varnish when cleaning the cables but only found evidence of it being applied to the cotton cording at the four terminal ends. The possibility of a wax based coating did not enter my mind but has attracted my attention now.

When cleaning up the cables, I started with the positive one and was noticing the cleaner was pulling a consistent brown stain onto the cloth. I thought that might be remnants of red dye, but when I switched to the negative cable I was still getting the same brown stain, not black like I thought I would.

If a wax based coating was applied to these cables, that opens up some interesting possibilities for me to explore.

Funny thing about ‘Chinese Red’. There seems to be enough interpretations of that colour out there to make its own colour chart! Grrr!
