One L84 was built by Albatros in Berlin-Johannisthal in 1930. It was designed to be armed, but no guns were fitted in accordance with the Paris agreements of 1925/1926. In September 1931 Albatros merged/was acquired by Focke-Wulf, becoming Focke-Wulf-Albatros. The merged company eventually reverted to the Focke-Wulf name.
Development of the aircraft was continued under the FW AL84 designation. At least six AL84-aircraft were built after 1935, using various engines. Aircraft #448 was fitted with a 600hp Rolls-Royce Kestrel III, aircraft #450 was fitted with a fuel-injected BMW engine. Deliveries to China were discussed, but never proceeded with.
