One of the most notable variants of the T1 Type 2 is the Samba. Samba is the name given the 21 and 23 window versions of the Type 2. The 23 window Samba was built until 1963 and the 21 window Samba was built from 1964 until 1967. These variants were considered to be the top of the line versions of the T1 Type 2 and were fitted with a cloth sunroof. It is very common to find Type 2s that have been converted to 21 or 23 window variants, yet only cars built until 1967 are considered to be original.
