Help: what is the ratio of this W116 Differential?

[ChasesDragons]

Hi all,
Could you have a look at the pics and tell me what ratio this W116 Diff is, please?

I'm not sure you can tell from the numbers. They will probably be just casting marks.

Without pulling the diff apart I suppose you could lock one half shaft and then rotate the input shaft [by a known amount] and then measure the rotation of the other half shaft.

Dunno.

The GF+ part is for sure a casting mark from George Fischer !
Don’t think as above you’ll get much from that ?
