Harmony products, and Kay products usually can't even be precisely dated to a specific year, except by identifying the model from vintage catalogs... except for the fact that they would sometimes use old stock photos of last year's model in the catalogs. So while they are helpful, they are not 100%.

I worked in quality assurace/quality controll for over thirty+ years manufacturing everything from tobacco products to medical devices.

Companys use a date code to identify manufacturs, sub assemblys and as manufacturing tracking devices.

When a company recieves a complaint they want to be able to trace it's production. They want to know who manufactured the sub assemblys, the shift, line, and time of manufacture and how many units were produced in the lot.

It's my opion that the "F and S" stamped in Harmony guitars refers to the shift, ("F=First and S=Second")not fall and spring. The shift is usfull as a tracking device where as the fall and spring is all but usless.

What kind of old guitar do I have? Is it valuable? How old is it? Where was it made? Is it worth repairing? Advice on buying new or used guitars, accessories, etc. [Note: While I can give some general info on approximate values of types of instruments, neither I nor anyone else can do an "appraisal" without actually seeing and handling the instrument] I have almost 40 years` experience as a player and afficianado. If I don`t have an answer myself, I can often refer people to other authoritative sources.
