Take the distributor cap off and look for a spark across the points
when you crank it. If you don't see one, check the points, condensor and
interconnections. Measure the voltage across the points. Should jump to
12 volts when the contacts open.
Then, remove the high voltage output of the coil and put a volt meter
with a high voltage, high impedance range across it and ground. You should
be getting high voltage out of the coil. If so, look downstream, perhaps
the brush between the cap and rotor, for the problem.
This will make more sense if you can find a schematic of a standard
coil/points/distributor system. (I'm assuming that's what '67 Spits have.

I am also the proud original owner of a 1976 Triumph Spitfire 1500 made
for the North American market. I've owned the car since college and have
recently decided to restore it for my son. This is a new hobby for me and
I am acquiring experience and tools as I go. I am certainly no expert.

working on dampening a vexing bonnet vibration the engine seemed to die --
just as it would if the car ran out of fuel or suffered from other form of
fuel starvation. Although the carb and fuel line are the obvious suspects
I can not seem to find evidence of spark in the ignition system.
