It's 16mm. There are several models over the years (this is one of the early ones).
Look for the dual film and tri film projectors in the "G" series. These bear a strong resemblence to a Siemens machine and were available in 8mm/9.5mm/16mm and even two blade/four blade and a three blade shutter version.
