Italian label under publisher De Ferrari & De Vega srl, with a catalogue of music by both Italian and German composers.
Seemingly the first two numbers in the catalogue number refers to the release year, whereas the two last refer to its relative position in the catalogue. I'm also guessing ST/M = Stereo/Mono.
i.e.
7612 is album 12, issued in 19
76.
