I'm trying to date a microcrowave oven that still works with no parts replaced built in the 70s. It is made by amana and the serial # starts with a B. The information that I have says that in the 70,s amana uses a Black Horse code to date the ovens. B would have been 70, L- 71, A-72........... The trouble is I dont know which would have been the first year. Would B have been 70 or 71or something else.
