With all of the walkers being posted I thought I might throw mine into the mix. Mine is very similar to the Star Wars version, the AT-ST from The Empire Strikes Back and Return of the Jedi.
Lots of parts from the spares box from all sorts of kits, the gun assembly from an older Tamiya Wespe I never finished and some sheet stock as well. The last photo was sloppily edited to remove the object holding the right side up to give a clear look at what this might end up like.
Just a fun distraction from the 'real world' modeling.
