As of my last knowledge update in September 2023, there is no specific set by LEGO with the number 970634. LEGO set numbers usually follow a specific format, but its possible that this number does not refer to an officially recognized set or it may be a typographical error. LEGO produces a wide variety of sets across numerous themes like City, Star Wars, Technic, Harry Potter, and more. Each set is uniquely numbered for identification. If youre looking for information on a particular set, it might help to double-check the set number or provide more details regarding the theme or description of the set youre interested in. LEGO also occasionally collaborates on exclusive sets or has regional special editions, so theres a chance that specific numbers could be related to such unique instances.
