I was into model rocketry during my high school years and even attended NARAM 6 and 7 in 1964 and 1965. I got back into it a little bit with my own kids 30 years ago and now I have grand kids interested. They found some of my old model rocketry supplies including some engines made by ProDyne Inc out of Utah. I think I bought them at NARAM 6 or 7 so they are 50 some years old. I have had them stored in a cool dry location all these years. They made a "Cyclone" and a "Hurricane" model. They are beautiful looking motors but I need help on the motor nomenclature. As an example they all seem to start with a BE lettering then numbers like 2.5-3 followed by a 0 which I assume is a booster or a a delay number like 4,5,6 etc So my question is what class motors are these? they are about 1 inch and 1 1/4 inch in diameter and have various lengths of 4-6 inches so I think they are too big to be B engines and I don't know what the BE stands for. I may test fire one of them to see if they still work. Here are some examples of the labels
BE - 2.5 -1 - 0
BE - 2.5 - 2 - 8
BE - 2.5 - 3 - 5
BE - 3.5 - 3 - 10
BE - 3.5 - 4 - 12
