Please explain how a steering column attachment fits with mechanical tower clock.
Sellers ultimately determine the categories where their items appear. Some sellers choose wisely; others not so much. It does not matter how specific or well-organized eBay categories are if sellers list items in the wrong categories.
You may find that searching using keywords, rather than simply browsing a category, can be effective. Choosing suitable keywords, narrowing to a particular category, then selecting relevant item-specific filter options can often allow you to find exactly what you are searching for without having to wade through lots of irrelevant listings.
I do not know anything about tower clocks, but this might be good place to start your search:
https://www.ebay.com/sch/261602/i.html?_from=R40&_nkw=tower.clock&LH_TitleDesc=0&_oac=1
That should find items in the Decorative Collectible Clock category that contain the term "tower clock" in the title or item-specifics. You can widen the search to include other categories, but that runs the risk of including lots of postcards of architectural tower clocks.
