Yes alas the Percival Vickers catalog never did appear on the Internet Archive site, probably funding issues.
I emailed Barrie Skelcher about the Percival Vickers catalogues a couple of years ago, here was his reply:
"It was back in 1993 / 4 that Glass Association member Peter Helm made some copies for me. I think they came from Manchester Museum, that is what my notes say but there is also a letter from Peter which refers to Tom Percivals copy which was a copy of Barbara Yates copy which in turn was a copy of an original which is now out out of sight.
What I now have is copy of Percival Vickers 1881 Cut Glass catalogue; an 1881(moulded glass);1893 Suplementary Catalogue of Moulded, Cut, Engraved, and Etched Flint Glass by P V Ltd.;Patterns of Moulded, Cut, Engraved Goods for Electro Plate Trade 1893; Glass Shades for Electric Light (1902), pages from a 1846 decanter and wine glass catalogue"
