Only one bass string scale for the M&H AA?

Hi Bill,

I do rescale and I also know there are several AA scales.  There
should be a number or letter at the plate tail (near the first (last)
bolt at the end of the casting near the bass bridge.  I think they are
numbers.

Serial and scale designation might have helped.

P.S.  What a mess, sorry about that.
