Opel Blitz 3 t A-Type Van
ROCO 1:87 Scale Vehicle Review

The ROCO 1:87 scale medium all-terrain truck Opel Blitz 3 t A-type with standardized van body is fitted with an LC-Koffer (mot.) Kfz. 305/… with walkway roof, introduced in 1933 as an office van, ambulance, dental clinic, warehouse, workshop van etc. for the German Luftwaffe, although rarely with the all-wheel drive chassis chosen by ROCO.
The vintage Opel Blitz 3-ton A-type truck with a closed, standardized body is widespread and can be found cheaply online or at flea markets. There‘s probably nothing wrong with using this medium truck with standardized van body as a German army radio truck, workshop, or kitchen vehicle in wargames.
