Cool Dryer, Peter
These were about as fancy as a Frigidaire dryer ever got, It has a 2 speed motor, a dual heating element, sprinkler system for dryer fires, no actually for damping clothing for ironing, Electronic dryness control [ made by Texas Instruments, same system as used on Lady Kenmore dryers in 1966-7 ] It also looks like it had a control behind the door to give you a no tumble setting.
FD dryers by this time had gotten fairly good overall, but were still no match for the reliability of WP & KM and GEs electric dryers and probably a few others. Weak spots in the FD dryers were the motor, front and rear drum bearings and slides, idler pulleys, and wiring in the heating element circuit.
I often said the good thing about a FD dryer was that their washers spun so well, usually a FD dryer paired with a FD washer lasted much longer that one that was paired with a BD WP-KM, GE-FF, WH FL washer etc.
In any event it is an awesome find Peter, I hope it is in as good a shape mechanically as it looks and you get to use it, there is still no beating the speed and size of a American dryer especially when used with a modern FAST spinning washer.
