I'm (planning on) building a 1/2 scale SA-14 Archer by North Coast Rocketry (2.6in. Version) and I'm looking for (mainly) the fin and strake dimensions. (Also some other stuff.)
I like the looks but I don't think I'll venture past Es... yet.
Sorry about your feet. Didn't mean to squish them too hard.
Also insufficient funds and lack of motivation to retrieve far away rockets.
Here's a list of the specs I need.
I'll add new information if I get it.

A drawing of the fin would help too, as would specs on the decals.
