Are tacho's all 3:1 ratio

Yes, and also the 350/500s.  Only exception were the Formula 500 that had the Veglia Competizione tach fitted, these were 5:1(iIrc) with the corresponding drive gears.

Yep, all 3:1.

None of the tach drives changed over the years, so all tachs the same, simple. :D  The worm drive gears were always integral with the cam/s, the 350/500 being the exception with its detachable gear.  AfaIk, the Veglia Competizione was never available in 3:1, so it was simply a case of producing a new set of gears for the Formula.

Agree with Piet but there are two different ratios for Smiths speed o meter which I think is where Paul is coming from

Well, it does say TACHO in the header... no mention of speedos.

Veglia Competitizone has 4:1 ratio.
