I see you have had several responses referring to gear-reduction 
starters and other such clever stuff.   Here's my take on the subject:

12.2V sounds a little low to me, and I think your battery is on the way 
out.   Jump-leads (unless they are the expensive heavy-duty ones) don't 
carry current all that well.   W=VxA: low V plus low A equals low W, and 
it is Watts, not Volts, that you need.

Try your big 4WD battery directly connected to your Triumph.   I solved 
a starting problem with my Herald convertible by using a spare battery 
from my Saab 9000 - rated at twice the capacity of the "correct" item.

Electrical brute force can overcome a multitude of problems!
