Model Numbers
Up until 1973 or 1974, the first and second digits following the 110. indicated the model year. Thereafter, it was the first and third, so the model number on this washer should read 110.724... I am drawing a blank on what the 2 signified, but it was the second digit on pretty much all BDs going forward; perhaps early DD models too. This is a 1974 model, and this year I believe was the last where you pushed the knob in to start. From then on, you pulled to start, just like with Maytags, GEs, and a host of others.
