I Stuart, that looks great the colour is spot on and the weathering looks great!! i'm in the process of doing a 1/35 Calliope and i will certainly be using your method for weathering to achieve the results i want.
I love all the U.S armour at the moment i've got 6 Shermans, one of which is almost done, and the rest to follow.
I would like to get all the collection in 1/35, i'm only missing M3 Lee, mate armoured car and a M18 Hornet then i'm done. Then starts the very long process in building them!! i surpose it will keep me busy for a couple of years.:cheeseygrin:
