These are simply business decisions based on factors we don't know much about...the health of Tony's business, how busy is his manufacturing, how much Savage was prepared to pay for the Fox name, etc.

Brand names are often pimped out for licensing fees, as the value of the operating business recedes. Or in any area that the core business doesn't touch. In this case, the value of the core operating business that uses the Fox name (Tony's replica Fox gun business) would likely have a remarkably small annual turnover despite the high regard and knowledge level we have of the brand name and Tony's A H Fox branded product.

The world cries out for such: he is needed & needed badly- the man who can carry a message to Garcia
