Yes, the mud is certainly a great option. What did you use to make it on you T-34/85 build? It sure looks great.
The seller has promised to send me the wrecked bits for the A1E1. It will be some weeks before they arrive and once here we will see what is what. If they take no measures to keep the new bits from battering each other, I may be no better off. I can certainly build what I have now but it will not be as nice as it should be.
