I remember the instructions calling for puttint the celophane tape on a piece of glass, spray painting it red, and using a straight-edge and hobby knife to cut it into strips.

I still have my original that I built in 74. As a last resort, I can trace the fin outline from my model. The real hassle in that is the inside curve that wraps the fin around the BT-5. I'm not sure where I put my contour guide. But, knowing the detail that Carl always paid attention to, I would venture that the Semroc fins are exact duplicates.

Hint #1: Do not use magician's flash paper for recovery wadding!

Hint #2: Clean your shoes after flyin' in that cow pasture - that ain't no dirt clod on the sole!
