A very nice example that one Nick, congrats and well done !!!
As far as the "mismatch" goes, it is perfectly original.
Guess they at the time, still had the bakelite steamvalves for the TE/Rollers in stock, while their stock of whistles, which was used on several other small engines, had already depleted, and been replaced by the later plastichandle version.
