I tested my MM cob bit, and it's too big. I'm betting they are 9mm O.D., as anywhere I found bits that list an O.D. are either 3mm or 9mm.
I'm guessing that these pipes are all pre-1980's or are 1970's era, and being cheap, drugstore pipes, didn't follow any kind of standard, or the standard sizes have changed over the years.
The label on the bottom of the bowl is too worn to read maker or model.
I'm thinking my only option is to take a 6mm filter (9mm O.D.) bit and sand it down to 6.5mm O.D. to fit, and with only 0.5mm of "wall" remaining, would be pretty fragile (but for $3 I'd be willing to try). Other option is to get one of the unfinished bits and do the same, hopefully leaving a thicker wall, while still fitting. Dunno the scoop on the unfinished ones.
I did email MM about it, and they basically said it's near impossible to find a bit for one brand that will fit another, and good luck in my search.
I also noticed yesterday while rehydration the 4 good new ones, then lightly waxing to lock in the moisture plus restore the little bit of shine, that the cob bowl had several sizeable cracks, although they don't appear to go all the way through as it held alcohol fine, and blocking the stem with my finger, and blowing hard with lips around the bowl, I felt no air leaks, so they seem to be on the outer part of the cob only, but that may change from expansion and contraction from use, would likely make the crack even deeper.
I'm told these were bought at an estate sale, so who knows how long they sat around unused and uncredited for, and the cob especially, drying out.
I friggin love tobacco!
