As part of my quest to find suitable models for Little Cold Wars, I picked up this tiny terror on eBay. For those of you unsure about what an ASU-57 looks like, here are a couple of photos of the real thing.
It was designed not long after the Great Patriotic War as a means of giving paratroops some armour support. It thus forms part of a Soviet tradition of experimenting with airborne armour - they've been at it since the 1930s. The tiny ASU was used as an assault gun and improvised APC by the pre-BMD Soviet paras. It must have been rather cramped in the latter role - the length including the gun barrel is under 3.5 metres and it is only 1.18 metres tall.
Here is the model - sent all the way from Bulgaria. It is a real Soviet-era diecast which had at some point (and quite understandably) lost part of it's gun barrel. Despite it's small size it scales out at around 1/43 - which is bang on for my LCW toys.
