Krupp M 305 engine and drivetrain for the Panzer 1 and variants.

[Foo Fighter]

G'day folks, My next trick, project, is the Panzer one in various converted forms, field fire truck for example. I am hoping for a lot more detail than the average so drivetrain and engine views/diagrams are on the wanted list. Does anyone know of a good source?

I have the two Panzer tracts books but would really appreciate something a lot more in depth if possible.

Stay well folks, you and yours.
