I had a Tomy Arthur once but it broke a long time ago. I now have a TrackMaster Arthur but he didn't have window stickers because it was a FP Arthur. They have the same shape of motor, the original Thomas motor, but the main thing is, that my Tomy Arthur had clearer lettering a and finer detail, while the FP Arthur had less detail.
^*Sorry, I have Hit Toys Arthur, also it runs very nicely.
Just checked.
