The Vega comparison doesn't hold water because the Vega was low priced or cheap compared to other makes and models. Sales of the Vega would be disappointing if it was priced around let say for arguement a Corvette!!! The Ithaca was NOT low priced its price was equal to or greater than the LC Smith or the Fox or the Parker and still people bought them over the other American doubles.
The Best Quality you might say, I'm not going there!!!
All the best
