Thanks...yeah, this was a strange one. When I opened it and saw Santa, I thought maybe there'd been a mistake and it was a tin bank or something in the box. Then I saw the Champak logo. I still have no idea why it bears absolutely no resemblance to the bus depicted on the outside.
Another thing that bugged me were the windows...some pointed forwards, some pointed backwards, and one was a regular rectangle. I think the artist must have said, "eh, good enough" more than once.
This is the only other place I've seen this object mentioned online, and I searched pretty extensively. Two bucks more than Foy's, but if you've got to have it, there's a way.
