Ex Borowski material on sale in London

I note that the October sale at Bonhams is now back on line. It includes a piece of jewellery formerly in the Elie Borowski collection (lot 245).

There is a particularly fine Roman bronze of Lar (lot 107). This has an interesting collecting history. It surfaced in a Swiss private collection in the 1980s before passing through "Hesperia Art Ltd, New York, early 1990s". Is this the same as Hesperia Arts of New York that sold a selection of antiquities in November 1990?
