Did a little bit of research and found one stamp similar to the ones you show ( https://www.rfrajola.com/wines/Wines.pdf ). The three line overprint has two items that you obviously already know, MDC for the Mission Dry Company in LA the date is also at the bottom. They call the stamp a pre-cancel so the mumber in the middle, which is not identified, appears to be a mystery. My guess is that it may have been an identifier connected to a certain area in the company. Since it's not explained it's possible nobody actually knows what it means. Possibly it's meant to be a new value for the stamp. But I'm just guessing and that's not what you want. I'll keep looking, there must be an explanation out there somewhere!! Good luck!
I found a black glass bottle on Ruby Lane from the same company: https://www.rubylane.com/item/131464-621 ... This is the quote given so at least we have a bit of information on the company, they did soda pop as well and used cool looking black glass bottles!!
"Offered for your consideration is this black glass soda bottle from Mission Dry Sparkling circa 1929. The Mission Dry Corporation grew out of the California Crushed Fruit Company in Los Angeles producing some of America's first soft drinks. Starting during Prohibition with Sparkling Orange, Mission Dry bottled their soft drinks in this unique black glass bottle.

Perhaps it was the number of the inked stamper, so that it could be traced back to a specific employee. Or possibly each bottle in a case would have an ascending number.
Maybe it was each production line had a different numbered stamp.
"Or possibly each bottle in a case would have an ascending number."
Ok, from this site https://www.stampcommunity.org/topic.asp ...
The answer from a post of the 08/05/2017 (revenuermd) The middle number is a rectification batch number.
The thread also mentions a book of wine stamp cancels.
Here are two wine stamps with unknown numbers, I have no idea what these numbers indicate.
See the Pick up Points (PUPs) with the arrows!
Does anybody have factual knowledge what these numbers indicate, and provide resource background?
