I don't usually buy Shapeways stuff because I don't like the way the print-lines stand out. These looked very good in the original picture, posted above, however, so I thought I'd take a chance...and I'm very glad I did. Lovely models with almost no perceivable print lines:
The machine gun in the Kfz 13 is very nice: grown from the bottom of the chassis with a little seat thrown in as well. No awkward sticking teeny-tiny pieces into teeny-tiny holes! Likewise, the antenna on the Kfz 14 comes integral to the vehicles, meaning that for both models all you have to do is undercoat and paint. The Kfz 14 also has a seat and radio-like boxes in the main compartment.
A bit pricey at an average of £10 each, but make a nice addition to my early war collection. Recommended.
