As a resident of the UK, how transferable is what you have for part II 10.? Is it simply a case of swapping out the relevant part of the US/UK tax treaty? I Imagine that it is fairly similar to the US/GER treaty. Any help would be appreciated,
Cheers

I discovered that the USA/Japan treaty has the same basic section format (ie Article 4-1 is the same) although the wording changes a little of course. Possibly it's a common layout for tax treaties.
If you google the German treaty & the UK treaty separately just compare the wording and make the necessary changes. The key parts of the treaty (as per what GeneralYeah's lawyer wrote) seem to be the Articles which (i) determine residency and (ii) the "other income" section.
Also, pay attention to details is important. For example, I am not a Japanese citizen, so I deleted "citizenship" from the 2nd part of #10.
