Hi Guys,
Small update, but lots of effort.
Here are a few pics of front fenders dry fitted. I am very impressed with fit and detail, although I will have to tear them off on my model:


Here are the tracks. 82 links now, with 2 additional ready to go. 2 punch out holes to fill on each. I will have to prime them to see how well I really did. I guess the real one had 85, but we'll see how they work once model is closer to completion. This was a lot of work. I just remembered that MiniArm makes a set of resin tracks for IS-2. I do not have them, but I think they are worth looking at to same on time:


ModelKasten tracks come with nice extras on each tree:



Those bolts can have many uses...

As for casting numbers, I've been trying to figure out exactly what they should be and where. I will probably go with MiniArm solution:


There are pics of turrets with letters too as not all had letters or lines. Some hulls have numbers on them as well, but I think you have to not go overboard with this...
Next I will more on to the texture, welds, and seams.
