Red bulgy error

[Super]

With all the discussion I have gleaned from this odd Bulgy and certainly not an expert on anything Thomas related, I have come up with a 'What If' possibility....what if this is just human error where there are two vats of plastic on the same production line , green/red, and someone simply hit the wrong button (red) when running the line for the green Bulgy. And if its like Chrisjo says...the error can't be seen in the boxed window the mistake was not caught for a while and many were sent out. This could explain why no one has seen them in a box....btw...kudos to Chrisjo for noticing that. So if this were the case we may not know how many actually made it out and there is still a chance that there may be some still new in the box out there. LOL...after rereading this theory, how many boxed factory errors will now pop up on the auction sites 😒
