Unofficial reissue label of unknown origin (rumoured to be German, some say Danish, but could be from anywhere!). Similar to Mason Records and Dorsey Records, their releases have no addresses, some have N©B as rights society, but the label code LC 04909 is for Motor Music (the German division of Universal that took over Metronome).
Walhalla is widely agreed to be a bootleg label, so should be listed as Unofficial releases with no Country of origin.
