That's not 110, that's about 130mm, possibly getting to a 140mm.
But hard to tell exactly from the tape measure.
To get a 110mm Syncos in the retro style you'll really be looking to the late 90s (GT era) probably matt finish.
Hinged high rise will be more common in that length from the DH side.
Though there should be a few 110mm normal style from, the tiny sized (15" maybe) bikes, I've not seen many about.
100mm on the other hand will certainly be a DH aimed hinged stem, in matt or silver from the end of the 90s.
