Becker radio question

I have one of these neat old radios, and note they
were an official option on our 73 RS. What I wondered is if anyone knows if the Becker Mexico of 1973 had a cassette player or not? The Becker radios seem to be in three flavors:
Europa (manual tuning, 5 - 6 button pre-set); Grand Prix (automatic tuning, 5 - 6 button pre-set) and the Mexico,
with automatic tuning, but no pre-sets and a cassette player instead. Given that the Grand Prix already has automatic tuning, it seems logical that Mexicos of the period had tape players. Anybody know for sure?
