fender 50s stratocaster

Genuine Fender Japan? Stratocaster. Neck + Body?
How I can know if my body is original Fender Start Fender Japan and Mexico? What I can search? I have a suscpision a guitar shop that sold me a Japanese reissue 50's I ordered a neck can be screwed Japanese to a Mexican national? I noticed that the tone pots are 250k, is this any help? Any info would be great and that put me out of this questioning.
Japanese Serial Numbers Decal peghead Note the absence of S, E, Series N. These are reserved for U.S. Fenders made in the corresponding decade. But keep in mind that the "E" and "N Series" sometimes seems the "made in Japan" models. This could have been a mistake on Fender part using the same prefix for both U.S. and Japan-made guitars. In any case, if it says "Made in Japan", then … JV + 5 digits = 1982 to 1984 SQ + 5 Digits = 1983 1984 E + 6 Digits = 1984 to 1987 A + 6 Digits = 1985 to 1986 B + 6 Digits = 1985 to 1986 C + 6 Digits = 1985 to 1986 F + 6 Digits = 1986 to 1987 G + 6 Digits = 1987 to 1988 H + 6 = Figures from 1988 to 1989 + I = 6 digits from 1989 until 1990 J + 6 Digits = 1989 to 1990 K + 6 Digits = 1990 to 1991 L = + 6 digits from 1991 to 1992 M + 6 Digits = 1992 1993 N + 6 Digits = 1993 to 1994 O + 6 = P + 6 Digits = 1994-1995 Figures from 1995 to 1996 Mexican Quotes Defenses SERIAL NUMBERS CIRCA 1990-1991 MN0 MN1 + 5 digits + 5 digits MN2 + 5 digits 1991-1992 1992-1993 1993-1994 MN3 MN4 + 5 digits + 5 digits + 5 digits 1994-1995 1995-1996 MN5 MN6 MN7 + 5 digits + 5 digits 1996-1997 1997-1998 MN8 + 5 digits 1998-1999 1999-2000 MN9 + 5 digits + 5 digits 2000-2001 MZ0 MZ1 MZ2 + 5 digits + 5 digits 2001-2002 2002-2003 2003-2004 Mz3 MZ4 + 5 digits MZ5 + 5 digits + 5 digits 2004-2005 2005-2006 Now if you take the neck of the guitar … pocket watches that fit the neck into the body and see if anything there as a Date / home / serial / etc. Look also at the heel of the neck and look for brands such as initials and date / origination / serial / etc then this type of work, you must be sure the guitar. you will find nothing under the pick guard and 250k pots are used in a single coil pick ups, while the 500K pots are used in humbuckers … ok that's all. Look for a series and see if they comply with the foregoing. And if you got a one jap. Awesome, rock and are getting more expensive all days. If you have an early 80's one that's even better, especially if it is a vintage reissue! $ $ $
