synchro tachometer for twin seahorses

[rolmops]

JB sorry to put this here,but it seems to be a question that only a few select OMC wizards may be able to answer.<br />Someone offered me a 1959 synchro tachometer that came of a setup with twin 35 larks,but from his description I did not quite understand what it is.<br />Has anybody ever heard of this type of tachometer?Is it one tachometer with two hands?(one for each engine)or is it two tachometers that sit side by side in one casing.Or is it hooked up to the engines and actually governs the fuel supply so both engines run at the same rpm?<br />thanks Rolmops
