Thanks gents for the kind words !
Hubert - thanks for the photos- these are a few I have never seen. The bottom one is of particular interest as some of the drums have three stripes and also appear to have lighter tops. I may do one of the drums in this fashion to break up the monotony. All the aircraft components in the photo seem to be IJN subjects so perhaps the stripes are peculiar to naval supply but I may play the artistic license card again and use the idea anyway !
Cheers - Richard
