- Two variations on the same test record (10 inch), probably issued in late 1951 or early 1952. This test record does not show the Minigroove label, but has a unique lay-out of its own; a rather odd choice as PPI had just started and the test record was meant to promote their new business.
- The first record shown features “Black Eyes” by the Bandi Balogh Gipsy Orchestra (A4), where the second record shown had “Black Eyes” replaced by the Zapakara’s song “Wang Sannie Dei”.
- The second test record had a regular release as Philips P 10000 R (1952), including the Minigroove logo.
- Source second test record: Sergio Derks. This test record came in a P 10000 R cover, where my copy, the first test record, does not have a cover. I’m not sure if the P 10000 R cover for this test record is correct, but I guess not. It was probably mixed up. Most likely it was released in a standard 78rpm sleeve.
