Sun Tacho

[23crate]

..
bear with me ....

down under we dont see too many Sun Tachos.

thinking that the "Greenline" is circa early mid 60s, im shopping round for one on ebay or similar - for the Stude

what id like to know -- somewhere i think ive seen a secret transmitter box that connects the tacho to everthing.

OR are they just simple 4 wire . coil batt, ign etc. and / or is the seccret transmitter box used for electronic ignition only ??

thanks !
