There was NEVER a 4-stager commercially produced by Estes, nor was there one by any of the other mainstream (Centuri, FSI, Semroc, AVI, etc) companies either.
The only Estes rocket CLOSE would be the Astron Farside or Comanche-3; one might get away with adding another booster to those on a totally windless day. The Farside would have to be B14 to B14 in the first two of four stages though. Good luck on getting those motors.
Centuri offered the 3-stage T-Bird and Arrow 300 kits. Also 3-stage, not 4.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
