The modern use of listing Matchbox Vehicles is using the code MB### (MAN# Numbers). Dodge Challenger is the first vehicles to use this, and as of now (2012,) we are in the 800s. Real Working Rigs, large 1:50ish scale cars with moving parts use RW###, and Skybusters, which are 1:50ish airplanes and helicopters, follows SB###. All cars before the Dodge Challenger follows LE###, which stands for Lesney. See mb-db.co.uk. for a complete list of all cars that follow MB### (Dodge Challenger - Present.) This coding is special to Matchbox use.
