Back in the earliest days of N Scale, Roskopf produced horse-drawn wagons in N Scale, which were imported and rebranded by Boyd Models, as well as Preiser and possibly Noch. Three of them appear on page 3 of Roskopf's 1967 catalog; a water wagon was added later. (Note that the cart is the same in all of them, with different details added.)
Where to Buy
Very likely impossible. You might have better luck finding an old Boyd item.
