Window fans

[saltysam]

Hi everyone.........was just wondering if anyone has one or a picture of a window fan that my parents had when i was a little tot.....it was made by Diehl and from what i remember was extremely heavy and had a blue square face plate in the front center of the fan in front of the motor. It had one knob in the center of the face plate that controled the speed and whether you wanted the fan to blow out or in...I remember they had purchased it somewhere between 1963-1965...if anyone could provide a picture i'd really appreciate it......thanks and bunch! mark
