I'd like to preface my response by admitting I don't have an answer to your original question but I would like to offer you some food for thought.
It would seem that the label stating made in Taiwan is important to you to verify your 'additional expenditure' for a better quality item was realized. Did the lathe you receive meet your expectations, or is it deficient/defective in some manner? If so, what is wrong other than the accessory issues previously mentioned? In essence, did you receive the type and quality of item you were seeking for the money you expended?
A label is just a label, and depending on who produced that label, may or not be truly representative of the object it is affixed to. Assuming your lathe is of Taiwan 'manufacture', it at least it uses Chinese castings and more probably uses Chinese finished sub-assemblies, relegating final fitting and assembly to Taiwan.
You probably also wouldn't know what company in Taiwan 'produced' the lathe. Perhaps the Taiwan producer couldn't/wouldn't build half as good a lathe as most Chinese companies. The Chinese can build good stuff, we just see most of the cheap bottom end stuff.
To put it simply, talk is cheap, it's the doin' that counts.
I wish you much enjoyment with your new lathe.
