Hi there,
found this on a german spoken board:

scroll down a bit till the tank comes. could be a good base for an iron daemon or a skullcracker.
did a quick research on amazon:
http://www.amazon.de/VsKfz-617-MENG-MODEL-SS001/dp/B006MEYYCI/ref=sr_1_1?ie=UTF8&qid=1367346664&sr=8-1&keywords=meng+1+35
the model is not cheap, but if you are looking for an alternative…why not.
