I inherited a self-propelled 22' Murray Legend, model 22753x92a. The label says "Date of manufacture 0562". Can it be a 1962 model? (It needs some work and I'm trying to make a fix-or-buy decision.) Has run great the 6 years I've had it.

My best guesstimate is May 1962

The label on my Murray (40620X20B) says: "Date of manufacture 0030". I don't suppose that means it's from 1930?
My guess was it's from May 2000. Can anyone confirm this?
