Does anyone know if the SdKfz 251/1 tow the 88mm anti tank gun.
Nope.
The towing capacity of a SdKfz 251 was only 2.7 tons. A 88mm Flak 18 weighs in at just under 5.5 tons. A 88mm PaK 43/41 weighed just over 4.8 tons.
I’ve seen them towing 75mm Pak 40’s. AFV Club has a nice combo kit.
TL: similar questions about towing the 8.8cm guns have come up before. Have a read here:

The SdKfz 251 could have towed 7.5cm Pak 40, 5cm Pak 38, 10.5cm leFH18, 15cm sIG33 or similar classed weapons.
