After the outbreak of the First World War, it became increasingly difficult to manage Welte's business in the USA. In 1917, after the USA entered WWI, Welte's business in the USA was confiscated and sold to the Auto Pneumatic Action Company New York. This led to the development of Welte's own licencee system, designed as a drawer system and based on the 88 standard scale similar to the Ampico - technically very similar to the Welte system. The Welte T100 (red) recordings could be recoded - as later for the Welte T98 (green) - and are therefore also available on Welte Licensee.
