You are correct. Hercules Kit # 1377. I still have mine from 1987.My first Estes rocket was the Astron Falcon boost glider... back around 1970 or so. Never flew it under rocket power but enjoyed gliding around the back yard. No telling what happened to it as it's been LONG gone.
However, I do still have what was probably my third Estes rocket built around 1980-84; a two-stage model with clear payload section (can't remember the name of the rocket... it's been too long ago). I didn't fly it until around 15 years ago for the first time. I didn't stage it properly and the booster section got stuck on the upper stage after booster burn-out, and it cooked the booster section quite thoroughly! I did rebuild it but the paint match is no longer perfect since the original white paint is somewhat yellowed with age. Oh well, it still flies!
Edit to add: Did some research and figured out the rocket name in question was the Hercules, kit #1377.
Same here, but got mine April 1967.My first model rocket was an Estes Scout (K-1).
I mail ordered it direct from Estes in January 1970. It took four weeks to get to me.
I decided not to follow the instructions completely which resulted in the rocket not being flyable.
I still have the model.
Viking 7 is ready for painting. Arcon 2 is rebuilt and in the steps of painting.Wow! Your Viking 7 is coming along nicely. Hopefully you’ll have a shot with it before March, while you still have that big field
