That makes some sense. Somewhere in one of the regulatory discussions on this board I remember reading that at one time the postal regs only allowed three motors "in a package". Hence, the three-motor tubes - often bundled together. Each WAS a separate package - it could travel separately as it was separately addressed and stamped.

Of course back then I didn't care about all of that - I was just glad to have the motors sent from southern Colorado to our post office box in NW New Mexico .
