In case anyone else is interested, I just learned from Aerus that the machines with the LX suffix (Ultralux LX/model 1521, Diplomat LX/model 1677, Genesis LX/model 1685, and Genesis LXe/model 1717) were manufactured in and around the 60th anniversary year (1984).
For those not familiar with Electrolux USA, the list does not include the model LX or LXI which were manufactured from 1952 to 1955.
