Plarail Metallic Thomas

Hey! So this is my first post of being in this community, I'm glad I was able to join so getting down to the topic I was browsing around looking for the Plarail 60th Anniversary Thomas when i found this other Plarail Metallic Thomas with two Clarebels with a him and both Clarebels each having their own plain box. I looked around the internet and also couldn't find an Metallic Annie with her own box and I haven't found any posts talking or mentioning this Thomas at all so could it just be an obscure rare metallic Thomas release?
