Interesting... it looks like they had two preliminary drafts for the ILS,
and the combination of them has become the published "Y" procedure
(it has vertical profile of the "Z" draft, and missed approach of the "Y"
draft, 19-dme arc of the "Z" draft, and minimums of the "Y" draft).
Thanks for the link!

There is, but it looks like its a "special", meaning it is not a public
procedure...see link below
