Sweden. Military Facit M13A II on cover, 1966, unissued complete envelope M13A II with nine separate squares for the national registration number, and reply-stamp model M13 (slightly different from the issued in 1980s). Never distributed due to that Sweden just a few years after printing changed the system to ten figures national registration number. The issue was destroyed in 1981 but a few have survived. Insignificant mark from tape on the reverse. EXHIBITION item. Ex. Zetterberg.
