LGB
G scale was introduced by Ernst Paul Lehmann Patentwerk under the brand name LGB and was intended for indoor and outdoor use. Lehman Patentwerk, founded in 1881, started producing LGB in 1968. The remains of the company were bought by Märklin and production of certain items continues.
The G name comes from the German word groß meaning "big". More recently some people have come to interpret it as standing for garden scale.
