Can anyone tell what year this aristocrat model lamp is from?

[Frank Fielden]

I recently bought an aristocrat lamp off a site called kijiji. The person I bought the lamp from told me that it was a 70's lamp. When I finally got the lamp and got around to checking it out, I noticed some things about the lamp that has lead me to believe that its not a 70s lamps. I happen to own another aristocrat lamp(red lava, clear liquid) that is from 1973 which I used to compare. The cap on the lamp is a screw on cap but the plug and the on switch is different from the lamp from 73. Does anyone have any idea when the aristocrat lamps used this certain plug and switch? on the bottom, the lamp is not date stamped, but has some number : 940562. Color combo: Blue liquid, yellow lava.

Definitely looks like a 90s Aristocrat (1994?) The 70s aristocrats had brown cords and I don’t believe the 70s ones ever came in the blue/yellow liquid/lava combo.

This is white/blue, not yellow/blue. The white can turn yellowish. Tilt the globe and look up into the cap, and there should be a date sticker. I believe this is 80s or very early 90s. I ADORE this lamp in this color, especially displayed alone in a dimly-lit living room.
