Wow, Chan! I only got #10 and an unnumbered kit. I guess Sheryl likes you best!
Seriously, this was a late '60s Centuri kit (see my comment before yours). It placed in an internats contest, but I doubt that the boat-tail was the "key" factor. Still, it has been a kit on my radar, but with the queue and flying contests, it was not high on a clone list for me.
Really needs a SEMROC B4-6 motor to make it a winner...
