The few comments on its page on the canon wiki have 2 places the name was revealed: Draco told Per it was seen "in the last episode on its data tag". You likely meant to say "in the last season", not the episode, but I doubt it was on the digital card.

Nerdfighter, however, said that his name was said on his paper shelving card from the eBay auction. Golive doesn't have images of every prop sold, so unfortunately we can't get proof from there. It might be on some somehow-still-there sold product pages somewhere on eBay, but there's no guarantee it's in one.
