This is not 100% accurate, since the blades may not be original or may have been made before or after the razor. The single-letter date codes are accompanied by a number, which corresponds to the quarter of the year. Date codes on blades (see above) also continued through this period.Gold plated Big Fellow intro'd as NEW Big Boy Deluxe. Typically you see a contract example NXSX-12345 the N-meaning naval XS is the designation for the bureau of Supplies and Accounts which is the bureau that oversees all the contracting bureaus the last designation represents the cognizant bureau which the account is for so an NXSX means is that the Bureau of supplies and Accounts awarded a contract on representing themselves the other naval bureaus are as follows with thier designation Aeronautics- A Supplies and Accounts-X Yards and Docks-Y Radio division-R Naval Personnel-P Other-S Medicine and Surgery-M Ordnance-O Secretary's Office-D you might see an NXSA which the contract was awarded through the Bureau of supplies and accounts for the bureau of the series of contracts you will encounter are NXSX NXSA NXSY NXSR NXSP NXSS NXSM NXSO NXSD Most of the bureaus contract through themselves their desigantions are as follows Aeronautics-OA Yards and docks-OY Ships-OBS Naval Personnel-OP Ordnance-ORD Marine corps-OM Coast Guard-TCG you will see these contracing bureau prefixes NOA NOY NOBS NOP NORD NOM NTCG There are also contract prefixes you will encounter they are 288, 140,145 and a few others these numbers represent the procurment station within the naval department. It does not make sense to me that there was two different styles of a fastners used by the navy that is why I think they are seperate service variations.I have only been able to identify the 288 prefix this Identifies Naval Aviation Supply Depot Philidelphia (NASD) these contracts represent contracts for the bureau of aeronautics. From my research, the original blue deck jacket was approved in (about April) 1939. In April 1943 they approved the change from the zipper to the buckles.On a piece of naval equipment you rarely see a date only a contract number. The problem with the zipper front is that zippers are not water-proof and there was no cloth cover over the zipper. The Olive Drab #7 foul weather gear (i.e., N-1 Deck jacket (officially, Jacket, Winter, N-1), et al) came out in mid-1943. The one I picked up this week is the one with the zipper.It is possible to date a piece using the contract number. One of the companies that makes reproductions of the buckle front model has the same story about the zipper version coming before the buckle front.For more in-depth information about the FDA Product Code, see Lessons 1, 3 and 4 of the FDA Office of Regulatory Affairs (ORA) Product Code Builder Tutorial (

Most people are considering becoming contractors so they get directed to Fed Biz Opps.However, blades made in those years were stamped with a date code: A for 1930, B for 1931, etc., plus 1-4 for the year quarter. In 1950 this system was expanded to include razors, too (see below).If a vintage razor is found with its original blades, the blade codes can be used to establish a rough date for the razor. Several other garments with that type of contract number system has been identified to a certain contractor and date and both have been 1940. I read one source that said my particular type of blue deck jacket pre-dated the 1943 ones, which had the galoshes type buckles (anyone who wore those as a kid in the 50's knows what those are). I read one source that said my particular type of blue deck jacket pre-dated the 1943 ones, which had the galoshes type buckles (anyone who wore those as a kid in the 50's knows what those are). I know of atleast two variants of the blue deck jacket and one is with the clasps or galosh style buckle.

From other contract labels like the one you posted it is probably a circa 1940 contract number which also fits the type of garment,the blue deck jacket.

When you do see a date with a contract number that is the month/day/and fiscal year the contract was awarded not the actual date of manufacture but most likely within a few example would be a date of Dec. I will post photos of that in a new thread on Navy deck jackets (it's about time we got one started).
