Ah the stash looking for a new 1/72 project I came across a thunder models US army tractor took me a while to work out where it came from ,then remembered said kit was purchased at Telford a couple of shows ago ,1/35 not really my bag but this was small and perfectly formed so worth stashing. So question is what colour primer would have been used before spraying with olive ,I quite fancy doing this one but using the old chipping fluid hense the question, haven't worked in this scale for years so could be interesting thanks Dave.
