That's an Estes Enterprises manufactured MMI Rock-A-Chute. These "Super" type B6 were introduced to the public by "Sam, the Spaceman"" with a MMI ad in American Modeler magazine in July 1959. So, potentially its that old.
July 24, 1959 is also significant because its the date that Vern Estes applied for his 'Toy Rocket Motor" patent 3,125,955.

July 30, 1959 is also an important date as its the date that G. Harry Stine lost control of MMI to the Keller familiy.
And of course finally, NARAM-1 was held in July 1959 In Denver Colorado and Stine states that the only motors present for NAR use were the Estes Enterprises motors of type A.8-3,A.8-4,B.8-0 and B.8-4.
The NAR TR-14 report I have has a table titled :
"Comparable Types"
Model Missiles,Inc
Type A4 = Type A.8-3
Super Type B6 = Type B.8-4
Upper Stage = Type A.8-4
Lower Stage = Type B.8-0
