I picked up a bunch of factory hood insulation retainers. As I was cleaning them I noticed some markings. I checked with a bag of originals I had and they have the markings too.
They are on the underside with a "B' on top and a number on the bottom. So far I have seen the number range from 4 to 32 (still cleaning the pile). The 32 negates a day of the month :), but might be a line or run number. I guess it is possible they had at least 32 injection stations and used the number for quality control.
Any thoughts?
Tool & Die: Mold and position numbers for QA/QC purposes would be my Guess.

Yup, mold cavity numbers.
