ZU-23-2 towed version (Russian)

I debated whether this should be a derivative of the ZU-23-2 in firing position, but all the files are different (the gun is in the travelling attitude, and the carriage has separate wheels), so I went for a new 'thing'.
This is a 1:76 version of the Russian ZU-23-2 anti-aircraft gun in towed configuration. It is based on the SketchUp library contribution by Archedyne (my thanks), but again heavily modified to make it printable (if a bit fiddly) and suitable for wargaming, or to have as a scale model.
Design process followed earlier offerings, with SketchUp used to partition the design, and 3D Builder to correct errors and add strengthening (my thanks again to AutoCAD and Microsoft for these tools). I think that the dimensions are right, and the model makes an attractive offering. Aligning the wheels is not ideal; I may revisit this later.
I now need a towing vehicle, as the Land Rover, though seen used in this role in some African countries, is not really suitable!
I hope this
