Panzer 1 Ausf. A Engine Photos

Hey everyone!

I’m going to build my Takom Pz. I Ausf. A 1:16 soon, and wondered if I could design the engine of this tank for 3D printing.

Sadly, there seems to be few photos of it on the Internet.
It should be the Krupp M 305.
I’m aware a similar engine was used in the Krupp Protze, but I’m specifically looking for photos of the tank configuration.

Could someone please provide me with better sources or even pictures and measurements? Any help is greatly appreciated.

Best regards
