It was probably produced in 1964. There's an oval stamped on the lever boss (The thing the lever is attached to in front of the trigger). It has one or two numbers plus a letter. The letter for 1964 is R. Savage started stamping these codes in 1949 with the letter A. They skipped O and Q.
The M stands for Monte Carlo. Your rifle would be a 99DL.
If the cocking indicator spring is broken they are hard to find here also. The rifle will function without it.
