  Some component changes during production. For instance the valve-line-up of DK91 DF91 DAF91 DL94 can come only after the European production. In 1949 the original valves could have been 1R5, 1T4, 1S5 and must have been 3V4, since the DL94 was produced after 1949.

  LT pack is  AD4 (about 150 hours)

  Trader 960 (22nd July 1950)  states released October 1949 and DL94 came in 1950 instead of the 3V4.
