Confirm its not a Vitesse 1600 gearbox first as if so it could all get much more complicated😭

Fair point I’ll get the digital callipers out and check.

Overdrive in a Herald is not period correct anyway (good mod though)

Factory-supplied optional extra back in the day, but most sold by far were non O/D.

I used a Spitfire iv box with J-type, again not 'period correct' but no-one sees anything bar the gearlever.

I didnt know that Colin, OD was available from Triumph on the Herald? I always thought it was just an optional extra on the Spitfire, Vitesse and GT6....

[johny]

Sorry Colin found several sources that say Herald was never offered with OD by the factory. I wonder if that was because the power wasnt there to be able to pull the weight and a higher ratio😭

and overdrive is not in the parts manual for 1360 as it is for spit vitesse and GT6. So never offered and not listed as an option in my 1966 ex works price list

hmmm, I know the comment was light hearted and expect you already know 😆 but I don’t think Heralds struggle with overdrive, even the Standard 8 and 10 with much less power were offered with it as an option.

Although I think we can all accept overdrive was never in the Herald options list, it is feasible you could get it as a special order if you were prepared to wait for your car to be built or as a dealer fit upgrade like the twin carb kit or servo brakes and other tweaks.

Not sure about Triumph doing it as even the official wiring diagrams dont include the appropriate section for overdrive. As for the power, especially in the earlier versions, I meant that Triumph could have considered the existing gearing of a Herald correct for a possible 4 people and luggage on board and the extra from overdrive would be wasted. After all they were billed as family cars rather than sports model werent they?

Dammit I hate it when that happens... now I have to go through years of old correspondence to find the owners who had the Herald with O/D from new; I have also seen it 'remarked upon' as available for the earlier cars but NOT the 13/60 however: until I can prove it, it's only fair to assume it never happened. I'll either put it up or shut it up!

Update: well it seems I remembered wrongly; overdrive was NEVER a factory option however in my own defence I'm now trying to find proof of at least one and possibly two Heralds that were converted at the dealership - I think before being received by their new owners, but may have been converted within a short space of ownership using Spitfire parts going by letters they sent me years back. I remember one being well upgraded with twin carbs etc and commenting that the later 12/50 would have been a good candidate. I'll keep sorting through boxes of correspondence in hopes that something turns up to confirm or clarify.
