I'm reading a copy of the American Modeler magazine, mar/apr 1963 and
G.Harry Stine mentions a new model rocket company called Scientific Amateur
Supply Co.(SASCO) in Ogden,Utah by what he calls a Thiokol propellant
chemist named John Rahkonen.

The motors are described as 1.3 lbs avg thrust / 4 sec thrust duration and 2.5 lbs avg thrust /6 sec thrust duration. This gives Total Impulses of 1.3 x 4 = 5.2 lb-sec and 2.5 x 6 = 15 lb-sec which I think reduces to 23 n-s and 66 n-s respectively. If this is correct they look like low E and mid- F .

Anybody ever heard or know anything about these motors? I assume they were composite motors.
