Fortunately, Global Machine Brokers has Bridgeport serial numbers from 1938-2002 on file, so we can help determine the age of your mill. If you're interested in figuring out the age of a machine, don't rely on hearsay or guesses from a previous owner - get the real age right now!
The original corporation was founded in Bridgeport, Connecticut and started selling its machines in 1938. It became famous in the following decades for small and medium sized vertical milling machines, with an iconic form of quill equipped multiple speed vertical milling head with a ram-on-turret mounting over a knee-and-column base. The American Precision Museum's biography of Rudolph Bannow reports that he conceived the iconic design in 1936 as the logical machine on which to mount the milling head already being built by the Bridgeport Pattern and Model Works (which he owned with partner Magnus Wahlstrom). The first Bridgeport milling machine (serial number 1) is on display at the Museum.
Here are some basic steps, although there are several ways to skin a mill. I wrote out the steps, then added a few videos at the end that more or less show how to pull a bridgeport apart piece by piece.
On TRAK bed mills, the serial number plate is located on the right side of the machine, on the machine base, between the table and the electrical box. On FHM5 and FHM7 bed mills the serial number plate is on the right side of the machine, on the column, between the table and the electrical box.

Alabama law requires the owner as listed on the title/registration to provide his/her driver's license or non-driver identification number. Companies registering vehicles are required to provide their federal employer identification number (FEIN).
When law enforcement agencies recover firearms that have been used in crimes, the agencies can usually trace the firearms to their first retail purchaser and use that information to investigate and solve the crime. Tracing is a powerful investigative tool, but it is dependent on the ability to identify firearms based on their serial numbers. Because the purveyors of the parts and kits used to make untraceable guns claim that they are not selling firearms, they also assert that these serialization requirements do not apply to them. Without a serial number, law enforcement cannot run a trace search on a firearm, making it difficult, if not impossible, in many cases to determine the chain of custody from the gun itself.
Other companies have also developed products such as pre-programmed milling machines that will produce a fully functional firearm receiver from unformed material with the press of a button. (These milling machines carve material in a subtractive manufacturing process while 3D printing adds material in an additive manufacturing process; both products seek to enable people to produce completed, unserialized firearm frames or receivers with the press of a button without ever undergoing a background check or other protections). 2b1af7f3a8
