Yes.
Carl Gustav recoilless rifle was created in 1948.
No published sn data that I know of.
Might be 1979 or it might not be.
Without having access to the manufacturing records of Carl Gustav, this would be difficult to determine based on serial number, and even more so without knowing the exact model of the rifle. On top of the chamber, the 6.5x55 Mauser rifles manufactured by Carl Gustav had a date printed below the ordinance mark. A closer examination of this part of the rifle may reveal this.
Need a detailed description of ALL markings.
