Pete,
The answer to your question is like so many others associated with Triumphs -
and this is, "it depends."
My own view is that as far back as the TR3 the choke cable was of the RGHI
(requires gentle human
intervention) type. However, history has proved conclusively that RGHI chokes
soon reverted to SBASAYPIO condition (shoot back as soon as you pull it out) -
especially if the choke pull-off springs were too strong.
Of course, in the decades that have passed since your car's build, it may have
been modified by a PO to the more 'respected' specification of PATTL (pull and
twist to lock) PATTL chokes were endemic to the British motor industry in the
60's and 70's and for the most part soon became FJOW (failure just outside
warranty) by which time there was little to choose between RGHI and SBASAYPIO
types.
If you are a purist and strive for *originality* an RGHI pattern is the one to
go for but I would recommend you upgrade it by adding a CPOAPOS conversion
(clothes peg on a piece of string) to give it the genuine 'period' look. Sure,
it'll upset the Concours Judges, but in my experience on the UK side of the
pond, they're mostly some damned obsessive that they judge all cars without
paying any heed at all to the original manufacturer's TIACAWCDI (this is as
cheap as we can do it) build policy.
So, the bottom line? I'd go for an RGHI choke and a CPOAPOS conversion - and
leave it at that :)

PS The Triumph Trans-AmeriCa Stag will next year complete its marathon journey
with a CPOAPOS choke set up. So much more in keeping with the car than furry
dice swinging from the rear view mirror and nodding dogs in the back window.
