Arc (5)

Italian label founded in 1964 by Ennio Melis.

How to identify the date of release:
Since a clear release date doesn't appear on most of the releases from 1964 to 1970 (especially 7"), it can be inferred from the matrix scheme, according to the following pattern:
PKAW identifies releases pressed in 1964
QKAW = 1965
RKAW = 1966
SKAW = 1967
TKAW = 1968
UKAW = 1969
ZKAW = 1970
