Need part number translation

I recently acquired a number of parts from a friend that passed away. One I cannot identify is lettered on the bag: NME4102. The Andover Norton website will not decode it regardless of which way I enter it. The parts are brass bushings, ID .865", OD 1.030" length 1.125". They don't appear to fit anywhere in an AMC gearbox. Can anybody decode this number into the current numbers or tell me what they fit?

Thanks, I did find the listing at a couple of Norton suppliers.

The "NME" is a tipoff. That stands for "Norton Motors Engine" parts. There are NMT (Norton Motors Twin) and simply NM prefix parts, too. These go back to Bracebridge Street,
