What letter is etched into the corner of the serial plate. It's where the blue dot in this pic is marked on the older metal plates, or above it on the sticky labels as shown on this pic. Not the red circled letter (that's the shaft length)
With that you'll get it aged dead on very easily by me or anybody else on here.
