Your Stuart is really looking great Chris ..... very clean build on the exterior and your interior is nicely weathered.
One small comment on the tracks before you get too far. Stuart tracks, like the Sherman tracks, are "live" so they have very little noticable sag. They should be a very straight and flat run across the top of the return rollers and skids. I have attached a pic that shows that. Hope this helps a bit.
Your build really makes me want to go out and get one of these little beauties !!!
Thanks for sharing Chris.
Happy Modelling and God Bless
Robert
