What's wrong with it? It's a fake. More generously, it's a "decorative reproduction". An unfortunate number of celestial navigation beginners have been burned by these decorative toys. You can see a "shiny" version on the website of the maker/distributor here: https://www.stanleylondon.com/ [...] .html (screen cap attached, with a few notations). I think the best analog of this company in the US would be the "Franklin Mint". Imagine if Sky & Telescope published a photo of "Newton's Telescope" and it turned out it was a dust-collector sold by the Franklin Mint. That would be bad.
