        British prices are _quite_ different than US prices (usually much
higher - by 50 to 100%).  Some more unusual (in the US) cars may be similar
in price, like the Stag.  (Though Stags seem to be overpriced; someone
locally is trying to sell his daily-driver stag for just under $10K - he used
to be trying to sell it for ~$7500 for years, with no buyers.)

        No, nor any other electrical changes.  It isn't an static overload;
amp draws (motor off, measured on the ammeter) are normal looking (low),
including the brakes.  It has the hallmarks of an intermittent short or
intermittent overload.  The heating (without blowing) inbetween the two blows
may well have been short-duration shorts; enough to heat it but not quite
enough to blow it.  Perhaps a wire is cutting itself on a sharp edge as it
bounces around.

        Seems like a possibility.  I plan to do a visual on all the brake-
circuit wiring before trying anything again.

        Actually, outside the fuse - solder flowed out of the metal cap at the
downstream end.  No melted plastic.

        Nope.  And after replacing the fuse, sitting still, the amp draws
all looked reasonable and it stayed cool.

        Right.  But an intermittent short looks a lot like a startup surge,
if it doesn't last too long.

        I think they were black; mine are body color, but the body was
repainted (poorly).  Note that they have this nobbley undercoating-type
finish below a certain point (the chrome strip I'm also missing?)

        This might have changed over the years.  Many (most?) cars will have
been repainted by now, so looking at one now isn't a good indicator.
