Yes its a true Crystal. Its a downtuned version of the 16045/16145
The 1 series came optional with the 40 km/h 16 speed overdrive transmission, instead of the 30 km/h 12 speed like the 16045
The designation 14045 was originally used on the UR4 prototype with the 7.3 liter long stroke engine in the late 70's, however the UR4 models werent produced untill early 90's at ZTS in Slovak, who built the Crystals from 1981 onwards. There was also a 9045 UR4 prototype built.
