The only seemingly available technical info for this model is in Volume 6 of the AORSM. Unfortunately no dial stringing diagram.

Tecnico manufacturers data sheets do exist but they are rare as.

Looks like you may need to use the Eclectic Empiricist Method!

Its always entertaining & I have only done a few hundred. It can be worked out on paper. However, one is best starting with the gang either fully open or closed. Bluetack is your friend. You hook the cordage onto a drum hook and then as the drum goes the other way you feed the cordage on. That can be drawn on paper. You may have to do a lap of the drum score; as there must be enough cordage on the drum for it to either take up, or let off cordage to allow the vanes to open & shut.

In which direction, S, or Z the turns around the driver are done Governs the direction the dial pointer will travel.

You really have to see it to make any detailed comment. Some of the manufacturers data sheets actually tell you the cordage length & that's helpful.

Photo may be helpful or check other sets similar.

The schematics are already in the forum at https://vintage-radio.com.au/default.asp?f=2&th=1207

But sadly, no stringing info.
