Andy,
When you say the coil seems quite warm, how warm do you mean? My coil is
always hot after running the car and I figure it's due to it being mounted
to the engine block via a metal mount. To me it feels like the coil's metal
case is the same temperature as the engine block. The top part (non metal)
of the coil is much cooler then the sides.

OK, it's not Triumph, but presumably a "generic" LBC situation.
A friend's '57 MGA died on the road yesterday and would not restart.
He'd told me he was experiencing some rough running when the car was warmed
up, and he also noted that the coil seemed quite warm to the touch.
When I got there, there was no spark at the plugs and virtually no spark on
the points, which were not opening much (if at all) and whose rubbing block
showed some wear. Fuel delivery seemed fine.
I changed the points (no easy feat roadside on the MGA's distributor) and
got great spark there...but nowhere else. I then substituted a known good
coil...and still got no spark at the plugs.
Distributor cap, wires and rotor all seem good, with no telltale signs of
damage, cracking or carbon tracking.
At this point, I'm thinking condensor. Does that make sense? It was one
thing that I just didn't even consider trying to change roadside, given the
location and orientation of the MGA distributor, lack of good tools on hand,
and darkness.
