But it is not 105?
It could be 105. This image was first shared on December 22, 2020, and was likely taken even earlier. The first image of 105 emerged around December 28, 2020. Its possible the pennant number was painted sometime in between. Or maybe it's a different unit althogether. TBH, I've lost track of the units long time ago due to heightened security and the large number of 055s being built.
