Round 2 is an American manufacturing company which produces scale models including die-cast, plastic, slot cars, and other hobby products.

Racing Champions subsequently made a decision to sell off the model kit brands succeeded from the Ertl, including AMT.

The brand was originally founded by Sports Car Club of America Hall of Famer Oscar Koveleski in 1958 and it also used to publish how-to magazines on model-car building.

Today the brand is owned by Round 2 and they produce aircraft model kits as well as 1/6 scale automotive engines.

[9] Lindberg brand was founded in the 1950s, succeeding O-Lin which was specialized in flying "stick and tissue" aircraft models.

In the 1990s, George Toteff of MPC acquired Lindberg and started producing 1:20 and 1:25 scale car kits.

After Ertl was purchased by Racing Champions which were focused on diecast model, MPC was sold to Round 2.

Since then it established a position as a model kit manufacturer of vehicles appearing in Star Trek franchise.

Thomas Lowe signed an agreement to use Polar Lights brand under Round 2 in 2008, along with AMT and MPC.

Since obtaining NASCAR license in 1991–92, Racing Champions went through success in the 1990s by manufacturing diecast models of stock cars in various scales such as 1:18, 1:24 and 1:64.

They also produced non-racing vehicles through Racing Champions Mint line, which was considered the most detailed 1:64 scale diecast model during the time.
