This is my understanding
My mother had an a-407 washer , it was a 1973 washer and indeed it had a white tub, the agitator is exactly like this one, they would say that it was an 18 pond capacity, which at the time was the largest they had. The old one did not have a crome strip or filter, just the plain old plain old.It also had the amber light, i used to put my finger over it, when I was a kid, i thought that it was neat to see the light shine through my finger

The newer machine that my mother currently has was purchased in 1987, a 412, same capacity as the old one, however, i know it has a blue tub, I helped pick it out. Same agitator, although, it does ot filter as good as the old one did, strange, but oh well.-----As far as the trim pieces, this is what i have seen. I once saw a 1968 model similar to my mother's old one, and indeed, it did have the crome trim, amber light, and the crome filter.Correct me if I am wrong. I belive that the higher end models, some years had the back lit contol pannel,the lower end models had either just the solid or the amber light. i think that there is a brochere in the archives someplace, that is the same one that this one came out of, 1978, that one may have been the top of the line model. The top for 1987 stopped at the 712, the dryer my mom has is that model #.btw, nice washer, enjoy it, they are really good machines, my mother has had hers for 20 years now, no complaints.Be good to it, and it will be good to you
