This is an A106. It's about as BOL as one could get and has the smaller tub. It's very small capacity by today's standards but if you're just washing clothes and no large bedding, it'll perform just fine.
This has a powerfin agitator and the transmission runs at 63 OPM's which provides very aggressive turnover in the smaller tub machines. The only '06 small tub machines that ran at 54 OPM's were produced between 1966 and October of 1967. Maytag used 63 OPM gears in all washers after this period from November 1967 until the end of this transmission design in July, 1989.
The timer knob is acrylic, which Maytag started using in November of 1971. All models went to a spun aluminum dial in March of '75 EXCEPT the 106 and 106S, so the age of this machine could span anywhere from 1971 to 1979.
Expect to at least replace the belts, motor carriage rollers, and damper pads. These are ignored on Maytags.
