At that time Record, Chorus and Athena all used the same shifters, there were no Record shifters.
There were several different types, friction, Syncro and retrofriction.
I am using Syncro I (7 speed) and it shifts fine with my C-Record derailleur. Maybe I was lucky as many can not get it working.

+1 I agree. Retro Friction can and does work but you need a bit of patience with it and it can be finicky.

are your shifters friction or retro friction? if you retro friction I would stick with those. if you take the off the bosses and they do not have the white nylon friction washers they are friction shifters.

to use Synchro you need to have inser that matches the freewheel you want to use and then a matching chain.

such as a (this may not be correct but is an example) a blue 6 speed insert you need a Suntour Ultra 6 FW and a Regina CX chain or a Shimano Dura Ace. or you may come across a red 6 spd insert in which case you need a Regina America FW and a REgina or Sedis chain.

pics?

All of the groups used Record shifters...there were no Chorus, Athena or Croce.

I've had one set of Syncros that worked well on an all-Record '89 Montello.

Since then, those I've had were a little balky,
and even when I matched the shifters/RD/cassette/chain, it didn't matter.

The shifting was good enough for me; once in a while I had to over shift and come back one. No biggie.

For someone who's been riding a 2x7 DA or a 2x8 600 tricolor with DT shifters,
it's not going to be quite as "automatic."
