sadly I have no idea. I got them through a lot.
That refreshment coach is a somewhat rare Trackmaster item. @Super, it says it has a Trackmaster model under the Merchandise section of the page. Very few images of it exist, and there's a certain minimum image quality required on the Wikia, so that could be why there's no picture in the gallery for it. It was only available in the "Rosie's Fun Fair Special" Trucks & Track pack, and was quickly discontinued. Of course, it's far from the rarest thing in the world, but not including products released by TOMY, you've got one pretty rare Trackmaster item, and in very good condition! I have seen it multiple times on eBay before, but every one of those times, the pictures showed that the stickers had suffered from fading, peeling, and ripping.
EDIT: To clarify, since I realize the eBay thing could be misinterpreted, and I can't verify it's exact rarity, I have seen it twice before in very bad condition and once used but decent condition over the last 3 years.
...I get really anxious about my accuracy sometimes :c
EDIT: After learning of several friends who don't even collect Trackmaster or really care for it, but have this item, I changed the "extremely rare" bits to simply "rare."
