Not quite a Savage but...

I think you are right about that one. It was kind of like Cadillac(sp.?) and Buick, same basic car, but the finish/standard features were of different levels, thus price the difference.

In boats there was, I think it was, Trojan and Silverton. There was a blow up between the two original partners and they parted ways. Who ever left who started his own company with very similar designs at first and then they each began to evolve in different directions. There are probably other similar examples as well.
