Hey Rudi,
The Germans converted many other "Beutepanzers" but most were assigned to 2nd line units stationed in France.
I guess it makes sense as any spare parts needed would have to come from cannibalization of other vehicles.
The small number converted probably speaks volumes as to how well thought of these conversions were.
Their top speed was kinda slow at 26 kph and short ranged at 150 kilometers when compared to German SP's.
If they were as successful as the German SP's, I guess more would have been produced.
Cheers
