Germany has two accessions. One looks like it matches the 'Acme' sent to the Czech seed bank - Accession No. LYC 1333 (
http://gbis.ipk-gatersleben.de/GBIS_...toScroll=0,267). It is red.
The other accession is number LYC 291, is listed as being added the same year as LYC 1333, but there is no descriptive information. Both are documentary dead-ends (at least online) . . . the country of origin is listed as unknown.
And after following this path, I am having a déjà vu moment . . . I am pretty sure I have been down this particular rabbit hole many years ago . . .
