The King tiger is 1/60 - it is the Corgi one stripped of its original terrible paint job. I opened up the turret hatch and used my own white metal afv tools. I mastered these and had them cast. The spare tracks are one part of a two part link system I did for the T34/ Su-100. I have a lot of the old Corgi Su-100's and the tracks really let them down. I just cut off one side of the teeth and they look just like tiger track blocks.
I
reuse a lot of original diecast models - not recasting though that would be pirating!

Happy to make anything to commission!
