Keller Construction Sets
Keller was a very early construction system. It consisted of stone bricks (like Richter) and also metal parts in some sets to make bridges. It was thus one of the first metal constructional toys in the world. The system was produced in Germany from about 1886 to 1914. The metal bridge parts were introduced in about 1890 with revised parts being produced from around 1896.
The photos and information below is reproduced from a document that David Hobson produced in 1999.
