Not only do I have quite a few Solido AMX-13s, but the 'fleet' includes a few broken DCA (self propelled AA) variants. A pair of turrets was duly removed.....
The casemates were glued on using PVA. They were weighted down overnight while the glue dried.
I mentioned the shape of the casemate. Turns out that the front is angled either side of the gun mount. I suspect, however, that the vehicle is sufficiently obscure that few people will know any better then I did. And let's be honest - I don't much care!
