Your rifle has
no Lever Boss Code. Savage stopped using Lever Boss Codes in 1970... and your rifle was manufactured in either late 1980 or early 1981 when Savage was making their "D" letter series rifles.
Savage began using the "letter series" ("A" through "G")... I.E., a letter in front of their serial numbers... in 1969, beginning with the letter "A" plus the rifle's serial number in January of 1969 and ending with the letter "G" plus a serial number in 2002.
There didn't seem to be any "time schedule" to how many years any letter was used. As an example, Savage used the letter "A" in front of their serial numbers for four years, 1969, 1970, 1971 and 1972. Yet, they used the letter "F" at the beginning of their Model 99s serial numbers for over 11 years.
As you can see, Savage was very
erratic with the "systems" they used. Often, they would pull a rifle off the final assembly line and set it aside for later use which would throw that rifle's serial number completely out of sequence and into another model year.
As an example, I found one Model 99 #7805xx with a Lever Boss Code of the letter "I" indicating a 1957 year of manufacture. Yet, that serial number (7805xx) series normally had letter "G" Lever Boss Code which would indicate a 1955 manufacturing year. I even found 900,000 series serial numbers in late 1955 and 1956, yet here in 1957 was a rifle with an 780,000 series serial number.
Go figure, eh?
Savage moved their manufacturing facilities from Chicopee Fall, Mass. to Westfield, Mass. (still their current location) in 1960. There is a general feeling among those who "know" that the best quality Model 99s were made PRIOR to the move from Chicopee Falls and that Model 99s with serial numbers of 1,000,000 or less were of better quality than the Model 99s that followed.
In addition, it is generally accepted that any Model 99 with the rotary magazine is of superior quality to any Model 99 with a box magazine.
