thomas and friends mini series

I've just been in my local supermarket and managed to find a bunch of 2016 wave 4, quite odd the numbers based on what I found start at least at 33 and go as high as at least 55. So the numbers overlap with those in wave 3, but they do not duplicate them as the models in the numbers that do overlap are different.

Does anyone know of a check list for this wave?

Well my own mini.ixbyix.com has Wave 4, and those numbers are about right (I've heard 26-59, with some gaps). What region are you in, if you don't mind my asking? Wave 4 has been spotted in Australia/New Zealand and in the UK with those numbers, that I've heard so far.

For 2016 Wave 4 production moved from Thailand to China, and the general speculation is that the different number scheme is related to the change to the new factory.
