Your introduction is incredibly easy to follow and improves on the direct summary of the item but also allows the reader to get extra information. You also corrected punctuation errors. You do the same with the following paragraph's detailing important bits of detail that were left out.
You have a balanced structure to each section, though you seem to definitely put more weight into the illustration section then the rest. I don't believe that is a wrong decision, due to the history seemingly being obscured but I would keep an eye out on other information you could either add into another section or pad out the currently existing sections.
The content is neutral and good.
I know this is incredibly hypocritical but you heavily use one set of sources from a specific website. If that is all there really is, understandable but I'd condense the sources a bit.
