I don't think this is an A407. Neighbors of mine had one. The button set up on theirs was similar to the washer in the ad, but it had 3 buttons for speed control, whereas this one looks like it may have the plate marked Automatic in place of buttons. According to the ad, there is a separate cycle for Delicate on the dial.
This washer is probably a Fabric Matic model which came out later on. I have no idea as to the actual model number.
Have a good one,
James
