Episode 5: The function test marklin crocodile CCS 800, SK 800, G 800, TT 800 - with zinc plague?

The new small series continues: Mega Unboxing, purchase of a collection from the 40s and 50s. This time it's time for a functional test... see if the old vintage locomotives really still run, or has the zinc plague struck again?
This series documents an unboxing of around 20 more or less rare Märklin locomotives and wagons. I was allowed to take over the collection of a deceased model railroad collector and present the various items here, starting with the unboxing.
