What a great find......I am puzzled for my own self...how many years was this control panel out?....my mother got her BOL in 1964, so I go with that as being the year it came out, but seeing some of these models like yours, concluding that hers may have been a leftover about a year or two older....hers only had 2 water levels/temps, one cycle, the agitator was black and the swirl vanes were tapered towards the top, the filter was white and had nothing written on it, also the dial did not light.....
I would like to find one like this control top, but instead of going thru all the re-storing, I think I would just switch the top with newer model....
