I've got numerous shots of my desert tan M1IP if you need them. I am in the process of super detailing the lower hull. Too bad no one makes correct early T-156 style tracks. If you look at the Tamiya M1 and M1A1 tracks (and Academy M1A1 copy) as well as the poor Esci M1 and M1A1 kits (long OOP), you will notice that the center guide is in the middle of each block instead of straddling two adjacent track blocks. I had to settle for a set of Trumpeter late style M1A1/2 T-158 tracks.
Some of the other faults that I'm correcting on the old Tamiya M1 chassis are the heater exhast, rear grills and tow pintle, bilge pump, fire extinguisher actuator, lifting rings, #1 side skirt tubing and the taillight guards. Here is a photo of some earlier work I did:
Right one is the one I worked on, left one is an unmodified one that was just painted. I've done a lot more to it ans will post more photos later.
