1983-1988(approx)
CENTERBRAND: As seen in the picture below the
words "MODEL 500T" are found over the "O" and "R" in the word "WORTH" which is prominently
displayed in the centerbrand. "WORTH" has outlined (ie not filled in) letters that in total
are about 51/2 inches long. A ® symbol is located in between the lower legs of the "H"
in "WORTH." Directly below the word "WORTH" are the words "TULLAHOMA, TENNESSEE MADE IN U.S.A."
in much smaller print, located below and between the "W" and "H" in the word "WORTH." To the
right of the centerbrand are the words "TENNESSEE" over "THUMPER" diagonally on the bat.

BARREL: As pictured below, the barrel of the bat from this time period bears three lines of
writing. The top level has the words "Hand Crafted" in script writing, the second level has
the player's name in block letters, the third and bottom level has the word "MODEL." (Note:
in the minor league version of the bats during this period the word "MODEL" with a model number
appears in place of the player's name.)

KNOB: The knob of the bat bears the player's initial over the last whole number (or whole
number and fraction) in the length of the bat (ie 5 = 35 inch bat; 4½ = 34½ inch
bat). Below the length code is the model number of the bat. (Note: some bats will not bear
the player's initials, but this is by mistake).
STRIPING: Worth bats from all eras also will bear striping to the left of the centerbrand.
There are two stripes during this period, each are approximately 3/16 of an inch wide and
circle the bat, they are about ½ of an inch apart and 6 inches to the left of the
centerbrand.

1988(approx)-1989
CENTERBRAND: the "WORTH" in the centerbrand is now solid rather than outlined with the ®
symbol remaining in the same position. A new trademark appeared over the word "WORTH" which
consisted of two rectangles leaning to the right to form a "W" with a circle on the left all
within a circle and directly above the "R" in "WORTH." A "TM" symbol was also placed within
this circle. Beneath the word "WORTH" were the words "MODEL 500T TULLAHOMA, TENNESSEE MADE IN
U.S.A." located below and between the "W" and the "H" in "WORTH." The diagonal words "TENNESSEE
THUMPER" are still to the right of the centerbrand, but "THUMPER" is in filled in type rather
than the outlined type. All the remaining labeling on the barrel and knob remained the same.

1990-1991
CENTERBRAND: In this period Worth removed the words "TENNESSEE THUMPER" from the right of the
centerbrand. Also the words "MODEL 500T" were removed from the string of words below "WORTH"
in the centerbrand. The remaining words "Tullahoma, TN Made in U.S.A.," now not all in caps,
were stretched to reach from below the "W" to the "H" in "WORTH." Everything else stayed the
same.
STRIPING: The striping was moved closer to the centerbrand of the bat. The barrel and knob
labeling stayed the same.
1992-1995
CENTERBRAND: As pictured below, a new logo to go above the word "WORTH" was created, this time
with two rectangles leaning to the left to form the letter "W," within a circle. There is no
longer a TM symbol with this logo. Further, the ® symbol formerly within the bottom legs
of the "H" in "WORTH" was moved to the right of the "H" and the type face for the word "WORTH"
was changed to a more square type. The remainder of the labeling stayed the same.
