I'm not sure how it's spelled exactly. I known none survive, but I should think model companies would make those, since they were used by Germans all the up to the beginning of WW2.
You spelled it right. None survived, but there is at least one replica in Poland (built mainly because one such vehicle was captured by the Poles in 1919). I’m not into models, but I guess some must exist. Ehrhardts from WW1 and built right after the war (in 1919) were used by the Germans, Russians and Poles for a few years after WW1, but surely not until the beginning of WW2, they would be very outdated. 33 Ehrhardts were produced (the prototype in 1915, 12 in 1917 and 20 in 1919).
