I think Lawrence is right, 1963 would be my guess, ONLY because the flange-lips on the top cover are angled inward ever so slightly, and that was a change made from 1962 to 1963 and remained that way until the bitter end.
1962's panel colors were black and chrome; 1963's were gray/white and chrome, so go figure this one that looks like it's black/white and chrome. It's almost a match to Robert's WA-755 but the dial is white instead of black. The white indicates that there is a possibility of an illuminated dial, but you'd have to ask the seller to be sure. By 1963 illuminated dials on Filter-Flo's were a dying breed. I'd love to get this model but 150 is kind of steep for a dryer this old and this far away. If it works this is a very fine performer. I'm posting some pictures of some very similar models and an ad that might be for this very model (without the courtesy of a model number, rats!). I'd guess this model number would be something like DA-717X; it has automatic control, a foot pedal and most likely a drum light.
