Okay, roller coaster time...
Model Rocket Industries was a '60s company. Paper tubes and balsa cones. I flew a model on a MRI B3-3 that barely cleared the rod and ejected on the ground. Model Products Corp. made plastic models among other products and bought MRI. MPC brought in G Harry Stine to design kits and be an advocate. MPC produced 18mm motors and a 13mm line in answer to the Estes 13mm Mimibrute motors. The MPC motors were longer so that they could make a mini-B. Around 3-3.5 nt-sec, IIRC.
MPC introduced many plastic parts as they made plastic models.
When MPC punted their model rocketry line, AVI was formed to continue the effort. Later on many products were incorporated into the Quest line. I have in my collection a MRI Zenith Two kit, the MPC Zenith Two kit, and the Quest version.
