1/35 39 45 pak 40 crew with long coats

If I was you, I would have gone for German Uniform Feldgrau if you prefer to stay with Model Masters.  I would add a drop or two of MM Light Gray to make it look more faded.  Keep in mind none of feldgrau looked the same just like khaki depending on how long they were out on the field. 

thanks unfortunatly my hobby shop does not carry it i did pick up some rlm 80 like a green i mix some black with it.
