I am looking to date this rifle. It has a strange 4 digit serial number.

The first digit is the letter l.
The second digit is the letter V.
The third digit looks like a flaming bomb U.S. Ordinance Marking pointing to the right.
The fourth digit looks like a pointed pellet pointing to the right.

These 4 digits are on the front of the receiver body, inside the trigger area, and under
the plastic butt plate in the stock. I would appreciate any and all info concerning this.
