This cartridge has a diamond tipped stylus, and although this label is not something I've seen, it seems to indicate a 3.2 Carat diamond. I honestly don't see this spec for the stylus documented in any of the manuals and spec sheets readily available to me, so I can't say for sure that this is the specification of the DL-103 currently available. There have been some different versions over the years available in different markets (I see that you're in Europe), and this may be one of them.
About the problem you're encountering. I see two possibilities:
1: The "gently used" cartridge is damaged and does not catch a groove, and therefore skates across the record.
2: The turntable is not set up properly for the new cartridge. If you replaced your old cartridge with this one, and did not make any adjustments, that may be your problem. You may want to double check the balance, tracking force, and anti-skate adjustments based on the specifications of the DL-103.
I hope this helps. Thanks!
