In this example the pickups were wound by operator #20 in the 23rd week of 1978. It wasn t until 1982 the slab board came back. Very early Singers from the 1850 s up until the start of prefix letters in 1900 had two serial numbers s w serial number dating. Be aware of another code found on these pots, 013446 s w serial number dating. I have also seen a D, along with an A on a Sunburst body. The compartment lid has black tolex lining on the tolex/maroon cases. They still feature the split shaft design the Kluson brand tuners had. Saddles do seem to have a stamp on the underside of them, 027037. In 1979 a notch was added for a ground wire lug in the control cavity and output jack cavity and a black shielding paint was sprayed into the cavities right over the lugs and wires that were soldered to them. Body Routings: In the 1970 s profiles of the pickup routings became slightly wide and squared on the ends. The last five digits are basically random. Only when they could spare the time would they continue with sewing machine production. When you have the neck pitch where you want it tighten the bottom screw.
Large Letter Stamps: Not 100% sure what these mean, but I have a theory they were used to grade a body prior to recieving a finish. CASES In the late 70 s Strats came in black tolex cases, which were made from laminated wood covered with black tolex. Pickups: Pickups bobbins on 1970 s Fenders are made of a gray fiber material, nicknamed gray bottoms. All Singers up until 1900 have no letter prefix and came from several factories around the world. Ignore all the FRR stamps you ll find on the neck base and in the neck pocket. The most likely answer is that the larger number was the total number of machines produced by Singers when they only had a few factories and could keep up with and control the production output from Britain and America. A sticker that has the serial number on it will also be present on the underside of the pickguard. The lower number may be the total production run up until that number of that particular model range. Pot Codes: MMMYYWW Example: 1377818 - In 1977 found on the side of the pots, moved to the bottom (and unfortunately sometimes covered with solder) in 1978. Your last chance to own a vintage Fender Stratocaster is with the guitars of the late 1970 s. Beginning in 1971 Stratocaster bridges were made of a zinc/aluminum/other cast metal. Antigua (523*) Sienna Sunburst (531) Sahara Taupe (585) - Models in this color had a four-bolt neck and trussrod adjustment was at the base. Cases of this era will feature a Fender logo on the bottom left corner.
In 1980 the entire pickguard got covered with shielding tape. Sometime in 1979 Fender switched to a black plastic molded case with black or maroon plush interior. I ve seen a C on a Monaco Yellow and a Sunburst... DATE CODES Neck & Body Stamps: WWYD Example: 0304 - Basically the same as the date portion of the nine digit neck stamp although in black ink. Singer s have never manage to shed light on these two numbers especially as many have the last three digits the same. An important thing to look for are the matching serial number stickers in the neck pocket and on the pickguard. I ve read three different sources regarding what the color coats and top coats were composed of, and all three were different. Then there is depot storage and shop sales. The company cleverly managed their production from all factories to coincide with the serial number flow. For shotguns with removeable barrels, the code will be valid for the manufacture of the barrel; maybe for the receiver, as barrels do get switched around. ... .
