Anybody know the approx. rim width specs of the hammond mouthpieces from 12 & larger? Thank you!

What exactly do you mean by "rim width?"

I can tell you that the 11's and 12's I have measured are .010 to .015 bigger than specs, as I measure inside diameter.

I suppose I meant outside rim diameter.

As a user, the 12 series tends to be Bach 5-ish.
Heavy on the -ish

Could it actually be that you're looking for the physical width of the rim itself? Outer Diameter (OD) minus Inner Diameter (ID), then that number divided by 2 gives you Rim Width (RW).

(OD-ID)÷2=RW

Maybe you already know this and just need the numbers to fill the blanks. If only I had a Hammond mouthpiece to measure... And a caliper...

I measured a rim width of 6.53 mm for the 12 series with my digital caliper.

That's .257 which is virtually the same as my standard tenor rims, .260.
