Browning Semi Auto 22 Barrel Lock Spring

F.N. began production of the 22 Semi-Auto Rifle.

No serial numbers are available.

In 1961, the codes for caliber were changed:
T=Long Rifle Caliber
E=Short Rifle Caliber
Example: 8T1000 = A 1968 22 Long Rifle Caliber Semi-Auto Rifle with serial number 1000.

T=Long Rifle Caliber
E=Short Rifle Caliber

1969 started using two digits for the date of manufacture: type of Auto-5:
T=Long Rifle Caliber
E=Short Rifle Caliber

This was then followed by the serial number beginning with 1000.
Example: 69T1000 = A 1969 22 Semi-Auto rifle in 22 Long Rifle Caliber with a serial number of 1000.

T=Long Rifle Caliber
E=Short Rifle Caliber

In 1974 production of the 22 Semi-Auto was moved to Miroku, Japan. The order of the serial number code was changed to:

1. Serial Number which started at 1000 for each year.
2. Two digit year code
3. Rifle type code: T=Long Rifle Caliber, E=Short Rifle Caliber

Example: 1000T74 = A 1974 22 Semi-Auto rifle in 22 Long Rifle Caliber with a serial number of 1000.

T=Long Rifle Caliber

In 1975 Browning standardized its serial number identification which it followed until 1998.

2. Date of Manufacture is a two digit code:
   Z=1, Y=2, X=3, W=4, V=5, T=6, R=7, P=8, N=9, M=0
3. 22 Semi-Auto Type:
   146=Grade 1
   246=Grade 2
   346=Grade 3
   646=Grade 6

Example: 1000T74 = A 1974 22 Semi-Auto rifle in 22 Long Rifle Caliber with a serial number of 1000.

Serial Number Example:
