Flipping stellar progress on the model at the moment, it's damn near building itself! It does help that I haven't had to add much in the way of extras or do any major modifications which is making this a very pleasant build.
As my replacement tracks arrived today I went on and got them made up. They are really nicely detailed and went together with no issues at all. As the M41 had a live track no sag should be seen so it worked out at 73 links per side to get the tight look needed.
The rest of the model is now almost done with just turret hatches, .50 cal and then some texture on the turret still to be done.
