Daniel's find bringing this topic back to life caused me to look at this thread for the first time.
I wrote the 1976 "Medal Collector" article referenced above [Ulsterman's January 30, 2008 post]. I confirm that not only were facts scarce when I wrote the piece but that 'official Hungarian sources' actively ignored/discouraged my inquiries. From the above discussions, it appears that I saw a cast base metal 'copy' medal; not a silver original. The original material submitted for publication was edited a bit for the article; don't recall [other than dropping the Spanish colors stripe from the ribbon description] whether any salient facts got omitted. Knowing that editor quite well, I doubt that he cut anything worth-while; he explained that 'the printer' inadvertently skipped part of the ribbon description.
Hundai's contribution certainly expands our understanding of this award and it's relative scarcity. As Gordon noted, the more we study, learn and -- especially -- share, the better our collective [sic!] knowledge.
