Drawing numbers can indicate the vintage of an item.
Typically on BAR Mags, the postwar Royal Typewriter magazine floorplates have a 55 series drawing number on them. Theres a few websites out there that explain the progression of drawing numbers, but, the basicis of it are
WW2 and before, had a letter and 5~ digits. The letter indicated the size of the paper the drawing was on.
Post WW2, had a 2 digit series replace the letter, such as 55, 71 as commonly seen.
Then came FSN's.
A combination of drawing number / item number as well as manufacturer are clear indicators of vintage of the item. For example, clear delineations can be made on BAR related items if they are made by Royal Typewriter vs NESA, Auto Ordnance, Winchester, Colt, Marlin Rockwell.... these can be used to determine rough vintage, WW1, WW2, Korea.... then the drawing numbers, and revision numbers, can be used to pinpoint a narrower date range of production on the item, assuming that there were revisions made.
In your case its abundantly clear the item and contract date associated with it. Typically, those magazines are only marked with a S on the magazine follower and floorplate.
