This sample has been known previously (see http://www.forodrim.org/daeron/mdtci.html#DTS84 ). The new picture has a better quality, though.

sure - I did not intend to share it as anything new, just as an interesting bit.

+Александр Запрягаев I read it as "with the very best wishes of JRR Tolkien..."

I'm surprised to see tehtar can be placed over an s-hook.

+Jan Sorondil Slaný If the preceding vowel is marked, why not.

I always treated s-hooks as being similar in function to signs like the tilde for preceding nasal, that is as a mark modifying the consonant tengwa itself, with which it forms an atomic unit. I thus considered s-hooks applicable only for cases, where the s is adjacent to the preceding consonant, and not a separate sign, which can also receive tehtar.
Apparently, I was wrong. I guess I should consider s-hooks as being simply an alternative glyph for the tengwa silmë.

Other instances of sa-rince carrying a tehta occur in DTS 10 and in DTS 50. Encoding-wise, we have distinguished between a spacing sa-rince (that can carry tehtar) and a combining sa-rince. On a tengwa like quesse, the combining sa-rince attaches below the lúva, while the spacing sa-rince attaches on the right side of the telco.
