Just to be pedantic, the Syncro moniker was dropped for the SL-01RE 8 speed shifters circa 1992 (with the micro adjusting knob.) I can understand why they get the Syncro tag though, the g-spring system is essentially the same as their predecessor's, just without the friction option. It was also the same system as used in the Ergopower levers that also debuted in 1992.
A forum member even managed to put the dual mode internals into a 10 speed shifter, thereby creating the world's only dual mode 10 speed downtube shifters!
I've never heard them called Syncro III, but sure, I guess they may have been - not by Campagnolo though.
The dual mode shifters like the OP's were also available in an 8 speed version with a larger barrel and 8 speed insert.
