thanks again, George, chuck in the cockpit photo's, I may have them,I may not better to be sure!
First item on the agenda, apparently the wing tanks have re-inforcing ? strips on the top and bottom as well as on the leading edge over the oil tank, so I found the smallest plasticard half round strip and cut these to length and rounded the front and back edges and glued these in place to simulate the raised strips, I may sand then down a tad yet to reduce the profile....
