It is a DE90. This was considered to be the BOL, so much so that I have no brochures on it. I do have parts lists, however. The interesting thing is that this dryer did everything that a DE306 did. It even used the same timer. Unlike earlier low-end halo of heat dryers that sported a galvanized zinc drum, this dryer used the same porcelain drum that even the 806 & 906 used! This dryer was manufactured from 1969 until 1976 when it was replaced with its "big load" replacement, the DE91. Also this model was only offered in electric. If you wanted a gas low-end dryer you had to move up to the DG306.
