And in the case of rotted horse manure smell from some types of old

Some pre war Philips radio sets had rubber-covered wiring that stank
like rotted manure when you touched it with a soldering iron. I have no
idea what they used in it that was different from other makes.

Any idea what the distinctive (neutral, not pleasant not unpleasant) smell
is of ex-services electronic equipment is (UK anyway). If you go down the
lines of a radio rally/ hamfest the pitch of the guys specialising in
selling military surplus is quite distinctive. Military tropicalisation ?
anti-fungal spray ? mothballing agent ?


There are two smells I associate with that sort of thing. One is
Chatterton's Compound, a sort of tar used to fill cable jointing boxes,
it was more common in government surplus stores.

The other comes from a shellac-based varnish that was used to
tropicalise paxolin tagboards, but I don't know the cause of that smell
because shellac is supposed to be odourless. It isn't a fungicide
additive because I have smelled it when opening up some equipment I
built myself a long time ago. I had tropicalised it with a varnish
which I made by dissolving shellac flakes in alcohol, there were no
other ingredients.
