of course they did, thanks for reminding me - I'd forgotten to look in all of the books :pb: I have books/CD's for Bagley, Sowerby, Davidson and some minor bits and pieces, but tend to overlook MW, as I don't have their data (which I believe is held in the States, or is that another factory's details?). The Sphinx was produced (originally) in the middle of the Victoria period and, I suspect, long before my piece (but that is just my personal opinion). Am sure mine doesn't show the sort of wear I'd expect from a genuine C19 piece of glass. I did look on Pamela's glaspavillon, but don't recall seeing any matt black pieces.
