Roco SWS

Roco HO scale SWS halftrack with 37mm AA gun.

This is a very common Roco.

But with a little imagination, and almost no work, it can be customized with just a spare tire on the front.  Makes a big difference with almost no work.  The Roco 234 armored cars have essentially the same tires, eight of them in fact.

Here is a larger modification.  MG shield on the front like a 251 series halftrack.

A Roco MG 42 in the shield.

Four large rockets in crates on the sides, not unlike the 251 series.  I have no evidence that the Germans ever did this, but they certainly could have done it.
