I gave the info as is. The auction dates from 2018, so you may want to consider contacting the auctioneer and ask where the info is coming from.
It is a plus for the information that the auctioneer is Slovak, therefore may have good access to local archives. However, there are also a few minuses. I got no relevant hits on Hailo plus Jugend. All the medals seem to have surfaced recently and the design is quite clumsy. It seems inspired by Goetz, but he would have done a much better job. There is the short, fat horse, the snake in the wrong place, the empty centre on the other side and most of all the clumsy runes that make the legend hard to read as well as the lack of capitalisation of Hailo and Kampfjahr.
