I don't know if it is true, but I believe that these were used on British WWII bombers (Lancaster?), but I can't tell you who actually made them.
They come up on eBay with some frequency (particularly the GB version), and are usually red or green, but I think that there was an orange version. The color used depended on which chassis you are replicating, and they switched from side to side, depending on what track was driven. Le Mans=right, Daytona=left, etc.
There are a few other threads on this site. Try the search function, and I'm sure you'll see what you need.
