Hola Scott,
Thanks for your kind coments,
Yes,I try to optimized the pieces for create this little scene.In this case preffering a small "scenario",with the original wall piece, about,10cmx5cms high is too large,I must considered to put any tank or vehicle,but in this moment its too work for me!.Too much time!.Its only an exercise after years out of the paint discipline.
About the colours of the oil barrel,sincerely, I not remember,where I see it ( obviously in a colour photo ),but I think that red and white colours must be used in signal traffic roads and warning signals.I think,maybe like a stop or caution custom signal.
Anyway,if some one can help us in this question always are welcomed
Maybe,the right question will be ..,Whats the colours of the oil barrels of the diverses petroleum companies in the 20-40 decades?. An rare question..,?
