[WIP/Dimensions Request]: Stormfly's tail missile

If anyone happens to have an intact Stormfly, I need the dimensions on the tail missile - mostly the shaft (length and diameter), vein (height and thickness), and notch (offset from end, depth, angle) - guessing and checking is suboptimal.
The design and outer bits I can do myself, though I wouldn't mind getting those dimensions too if my benefactor is feeling generous :-)

Naturally once I have the dimensions I'll publish the model for the common good; I've provided as much as I've been able
