Famos 90
The Famos 90 burner is very similar to the Famos 88, The wick knob has either a moulded plastic insert with no markings, or a flat knob insert with a quite modernistic, almost art deco, Famos logo printed on it, which is a contrast with the ornateness of the burner. The table lamp now has the air holes around the base of the font.

Famos 90a
The Famos 90a is a transitional model between the Famos 90 and the Famos 120. Although it retains the gallery lifter, the wick raiser mechanism uses spur gears like the Famos 120, and the knob is like the Famos 120 with a plain red plastic insert..
