Standard L.R. Construction Sets

Standard L.R. was an unusual simple construction system. It used indentations and clips to join parts together. It was made in France from the early 1930s to (probably) the mid 1950s

Jouets L.R. (the manufacturer of Standard L.R.) was founded by Louis Roussy in 1926 with the factory being in Trappes, France and with offices in Paris. The two letters, L.R., are the initials of Louis Roussy and serve as a trademark for the various names of the company's creations. His family was the owner of Nestlé and his uncle is Gustave Roussy, the well known doctor. Standard L.R. is a patent of Louis Roussy and René Trubert (the technical engineer) in February 1933. The company Jouets L.R. closed down in 1956. It is not certain when production of Standard L.R. stopped. It could be anytime between August 1949 and June 1956 when the factory shut. The company Jouets L.R. closed down all operations in 1956.
