In 1996 Märklin released a limited Großbaukasten 10821 dedicated to Vienna’s famed Prater wheel. The set shipped in a wooden crate with a dedicated instruction book (print ref. 601144 11/96). The finished model is substantial—about L 132 × T 72 × H 136 cm—and was engineered for continuous operation. It reproduces the prototype’s cabin count at 15 gondolas (the comparison comes from a larger custom build that notes “30 gondeln, nicht nur 15”). Collectors often cite a parts count of ~5,700 pieces, underscoring why this is regarded as one of Märklin’s most ambitious construction sets.

Long before 10821, a Ferris-wheel-style model appeared in the classic Anleitungsheft Nr. 71b as the „Große Radschaukel“ (see the discussion and pointer to p. 134)
A Ferris-wheel-style model appeared in early Märklin manuals (e.g., Anleitung 71b), discussed with photos in Schrauber & Sammler no. 20.

Built with Märklin/Metallus components. An 8 mm steel shaft running on ball bearings was used for smoother, stiffer operation; a bushed wheel was added on the same 8 mm shaft. The transmission uses Metallus chain (p/n 4900-02). Supplementary 3D-printed parts were used where equivalent metal components were unavailable.
