The Model 11 was a bad gun that lost money. Killed so many users they had the nickname of widowmaker. Wow, what a flop!
The Model 40 was an underdeveloped gun that lost money. They never really got started. It was a failure.
The Model 50 was a good working autoloader, that must have lost money. That makes it a commercial failure.
The Model 1400 was a complete POS. Counterfit. Not worthy of the Winchester name. The same design ethics as a Chevrolet Vega or a Bic lighter. But it was, by Winchester standards, a complete success. It made lots of money and was in production about thirty years. I think they sold two million or more of them.
Now, if you want to talk Winchester commercial disaster, not just a mere failure, let's consider the Super X Model One. They only made about 90,000 of them, which was a good thing for Winchester as they lost money on every one of them, in fact they lost millions and millions of dollars, but it was a helluva gun. I think the best gas operated target gun ever made. But the guy in charge of the SX1 program, whoever he was, deserved to be fired. For Winchester, it was their greatest failure ever.
Any gun is a failure that fails to make money for the manufacturer. That's the reason they make the guns, you know? :wink:
