This is another home run for PSC. Great little tank. The only problem is there is so many wasted parts in this kit. Basically you can build one complete Stuart. Then throw the rest of parts in the trash. But if you can create a new lower hull you could be in luck. Could be possible to make a British tow vehicle, a Kangaroo, and Recce Stuart. Another problem for me was that the assembly instructions are printed inside of the box... Good thing I looked before throwing out the box. Attached the instructions for construction below. Now you will be able to see how to make the different variants.
There are many more variants of the M5. Check out this link. M3_Stuart
