Is this for keeping double band in sync ? One roller for the film, the other for the magnetic perf tape ?

Yes. Synching double band (image and sound) would be my guess, too.

Agree with above comments.
Synchronisers were used to keep picture and sound tracks in sync during editing, although most editing benches would have used a synchroniser with more than two "gangs".

Thank you for the answers. Not easy to really picture how it works but at least I have the idea. The seller doesn't seem to know what it is.

Here is a film showing the make up for a 16mm release print from an A and a B roll. This is done to not show a join between shots.

It's a sync block. That's a two gang, but a four gang is better for mixing.
