Possible. According to my book on Hungarian armor 12 serial numbers are mentioned in Hungarian period documents. But true is I check only one book. Just realize I got at least one more in which I should check. As I said, Hungarians got ar least 70000 Poles on their territory. Surely, most able escaped to west, but for sure they should be able to get at least company if not battalion of volunteers. My point just is for now Hungarian logistic situation is hard so they need to transport what got combat value. Maybe when Slovaks jump in situation improve as another 4 railway lines will be open. Not all at once for sure as they are spread from west to east but as part of Polands are liberated... However at least one railway tunnel was destroyed in 1939 and repaired only in 1943.
