I notice the liberal use of sequins in the torah cover, in the crown, under the lions, and making up the garland vase.
This is similar to a sequined torah cover from the early 1900s, found at a synagogue in the Lower East Side of New York City:
It is also similar to a torah cover that is in the collection of the Jewish Museum of Maryland, though there is no date mentioned in the website listing:
I would think there are textile historians here in the US who can tell you when those types of sequins became available, to at least give you an early date for the cover.
