DISK CUTTING LATHE AM 131
(Print ID = S 261/1959/500)
Dies ist ein erster kleiner Prospekt (natürlich noch in Englisch) oder auch nur ein Datenblatt für den ganz neuen südamerikanischen Markt, den Heinz Schleusner ab 1961 von Peru (Lima) aus aufgebaut hatte.
Der Markt für solche Platten-Schneid-Maschinen war dort deutlich kleiner als bei uns in Deutschland (West), weil einfach (damals wie auch heute) der Wohlstand fehlte.
Und als ab Ende 1963 die neue Philips CC-Kassette den Durchbruch anstrebte (eher ab 1965/1966), war in Süd- und Mittelamerika die Langspielplatte und auch die Single beinahe "gestorben".
Die Platten (und die Abspielgeräte) waren einfach zu teuer und man konnte auch nicht aufnehmen bzw. duplizieren. Die Qualität der Musik spielte in diesen Ländern keine große Rolle.
