1954 Russian Raguda (Rainbow) Field Sequential Color Set

In 1954 Russia built its first color sets. Named "Raguda", which means rainbow, the sets used the field sequential method. This information is from various Russian websites, one of which has a description (in Russian) of the system. The system was experimental, and only a few sets were made. At least one survives. Click for a technical manual or a page describing the set (in Czech).
