any idea what these are from?

[JMan1365]

was wondering if any of you would know what these came off of? I can get a few more pictures if needed but it'll be a few days as I'll have to enlarge the negatives first

Hard to tell at that angle, and without an idea of dimensions, but they look at bit like 'Sergeant Fletcher' wing tanks as used on the F4 Phantom, missing the end cones.
