This is one super deal from PSO. Allows five versions of the 251 to be made. The basic infantry model, the mortar carrier, the 37mm antitank close support weapon, the flammenwerfer, and the stummel. The detail on these kits is excellent as usual with lots of options and they assemble smoothly. Lack of clear instructions is a bit of a downer, But the real bonus was my box included 5 sprues, which allowed me to make 5 full vehicles, instead of the four that were advertised on the box.
