@PedroA – Pedro,
You have a great start on your Stug III. I have one of the earlier Trumpy Stugs in the stash but will be using that for a conversion. Nice kits. I have used styrene strip for railing in my past builds but the photo-etch strips are to scale and is far stronger than styrene. What adhesive did you use to attach the railing with?
Great idea with the cast copied tracks – saw your step-by-step for making them in resin over at your blog spot. Are you using a resin with a longer set up time for this type of casting? The boxes are also a good idea as you can make more copies, as you need them for other models.
Pedro, sorry I’m late on this one. I scanned a few photographs of the Stug III Ausf E in winter camouflage. Hope these will be of some use to you.

This Stug III Ausf E photographed in Russia late 1942 with applied paste white wash. The markings were usually masked off leaving some of the base color showing through. Note the spare wheels up front along the side of the superstructure. This was a common field applied modification leaving the rear area free of the spare wheels for the bulky stowage. The spare wheels also have the white wash applied to them including the tires.

This is another example of the white wash being used to camouflage the vehicle. Note the extra spare track links on the rear of the vehicle used to protect the stowage. This vehicle also has had the same field modification for storing the spare wheels up front along the sides of the superstructure. On this vehicle the spare wheels are unpainted with the white wash paste. This unit applied the names of big cats to their vehicles - Löwe (Lion), Puma, and Leopard.

Due to shortages of supplies most vehicles sported just the snow for camouflage and other used white bed, table or blanket sheets for camouflage. Of interest is the extra long extension tubes (sunshades) applied to the telescope sights to cut down on the snows glare.
There appear to be no set rule for applying the white wash paste to the vehicles. Stripes, spots, cloud patterns and ‘X’s were used to conceal the vehicle from the enemies ground and air power. The gun cleaning rods and tools seem not to have been painted over in most cases.
Hope this helps,
