This is incredible information. Thanks very much for sending it along! Our lathe does indeed display the W.E.F and L.Q.R. Inspector stamps, near the Navy anchor mark.so we know the inspectors initials, at least.
Now the final marking is still interesting: “ MA E127”
Wondering if this stamping appears on other SB lathes?
Here at Pearl Harbor, all equipment usually ends up with a separate facilities inventory ID number either stamped or riveted to the equipment - sort of like the unit identification numbers painted on the bumpers of army trucks.
However, none of the PH facility tags match the MA E127 number sequence. So maybe it’s a ship number or some other unit designator??
Steve, again, many thanks for the work you accomplish, tracking the history of these old lathes.

Copy of old post on the subject:
In the serial number file, which I am always several years behind on, I only list the information I am provided with. The posts with my personal opinions are also kind of old when we were first chatting about the stamps. My opinions are subject to change…lol, and I have flipped flopped somewhat on this subject in regards to the JAN stamp, which would/could appear to be a military spec stamp. Inspectors at the military arms or provision suppliers, used their initials. The inspectors could be military or military employed civilian, not important, the point is they are inspection and acceptance stamps. See info below.
It is well known that SBL was a major machine supplier with the Navy.

Web search Info found on Inspector stamps:
For Sale: Oficial U.S. Navy inspector's hammer with dies at each end. The large die is 1 3/16" W x 1 6/16" H. The small die is 9/16" W x 9/16" H. The mark stamped on an item indicated it has passed inspection.
It is reported by companies that made these items during WW II, that the inspectors kept these tools under lock and key, and that they never had access to them. At the end of the War, when the inspectors left the plants, this tool went with them
JAN = joint Army-Navy [specification]
Inspection and acceptance marks:
The US Navy 'Anchor' stamp indicated the item had been inspected and accepted by the US Navy.
The U.S. Navy's inspector's mark -- the initials "U S" with a small anchor between
Small arms of the United States Army and Navy bear an initial or initials which are called inspector’s marks. These marks appear on stocks, grips or metal parts. Some arms, especially older ones, have more than one inspector’s initial or initials.
The Army and Navy purchased arms from commercial outlets and also contracted directly with the manufacturers. The Navy also purchased some arms from the Army. From the early days of 1831, most small arms contract inspectors were civilians or Springfield Armory employees. Officers who served as inspectors were from the Army Ordnance Department or the Navy Bureau of Ordnance. There were also sub-inspectors who had regular jobs at Springfield Armory, and small arms inspection was in addition to their regular duties. Army or Navy inspectors had control over all sub-inspectors.
It must be noted that in some cases, these inspectors are civilian personnel. Others will be military personnel

The Hawaii Railway Society, in Ewa Beach, has an old surplus WWII Pearl Harbor SB 10L in our back shops. I would like to come up with some explanation of the WW II stampings on the end side of the bed/ways.
Can anyone advise what these markings may indicate?
FYI, we know the lathe was produced in 1942, and came from the Navy to the HRS from the Pearl Harbor naval machine shop some years ago. But I haven’t been able to interpret the markings that have been added since new, or find anyone who knows what they mean.
Clearly the lathe contributed to the war effort in the Pacific. I think it would be cool to learn more about where it has been used.
Thanks much if anyone can shed any light on its history.
