Charles Merzbach was a New York distributor of diecast models in the USA. His company distributed a variety of different brands in direct competition to Fred Bronner's Lesney offerings in the 1970s. Merzbach marketed Majorette brand castings as "Fastwheels" and is often credited with developing that brand name. He also distibuted Faller's 'Hit Car" and Siku brand castings.
In the 1980s, he marketed Playart made castings as Charmerz "Super Scale Models". Charmerz is a combination of his first and last names. As singles they were called "Super Singles" and as pairs "Super Tandems".
