[Trombone-l] King M series MPs?

[Emil Orth]

Hey fellers, I've looked all over the place for some kind of a site or comparison chart that tells the approximate size of the M- series MPs....No luck, so far.  I know there must be an expert on these on our list.  Would you please reply???either on the list or to me individually.  Thank you.
