If you check Ebay, there are several Euro sources selling small quantities of this core.

Micrometals will sell direct, and even give free samples in small quantities (if in stock),
at least in the USA. Sometimes only distributors will have stock of a particular part,
but they can tell you who does have parts in stock.

I was told that most of what Amidon sells is rebranded Micrometals.
Sorry, I don't have a cross reference.

Mouser has FairRite, that might be an alternate source.

Fair-Rite sell ferrite cores - they don't make any iron powder cores.
