[Boatanchors] Western Electric (Nassau) solder

[Jim Haynes]

There was also something called 1-A Fire Detection Wire which appeared to
be simply rosin core solder with a red fabric insulating jacket over it.
This was run over cable forms with the idea that it would melt in case
of fire and set off an alarm.  I say it looked like ordinary solder, but
I don't know if the melting point was the same.
