KOUTLOSH: Na mě v zásadě wiki plivla tohle:
"The Thompson-Center Contender is a break-action single-shot pistol or rifle that was introduced in 1967 by Thompson Center Arms. It can be chambered in calibers from .22 Long Rifle through .45-70 Government.
In the 1960s, Warren Center developed an unusual break-action, single-shot pistol that would became known as the Contender in his basement workshop. In 1965, Warren Center joined the K.W. Thompson Tool Company, and together, they announced Warren Center's Contender pistol in 1967. Although it sold for more than comparable hunting revolvers, the flexibility of being able to shoot multiple calibers by simply changing the barrel and sights and its higher accuracy soon made it popular with handgun hunters. As K.W. Thompson Tool began marketing Center's Contender pistol, the company name was changed to Thompson/Center Arms Company."
Předpokládám že jde tedy o nějakou licenční výrobu či co.
