I think the bottom line is that most everyone ASSUMED that there was a difference. Bottom line, if you put a "B" motor in your rocket and it flew, who cared who made it as long as it performed as it was suppose to.

My father told me a story when he lived in California, he worked for a orange juice packing plant , one company making juice under 18 different brand labels.

In todays corporate world, who knows who makes what, especially with so many mergers and company "secrets".

I think we would all be amazed if we knew the backgrounds of many of our well known brands.

And in todays marketplace, you try to get as much business that you can, even if it's a rival.
