The only ink found so far with the help of the Percival Vickers catalogues, this is shown as pattern 47 in the 1881 catalogue - or possibly 48, both very similar.
The density value is contributory for the attribution.
Missing its lid, which was glass with studs on the rim, and a star pattern on the top.
Also missing the ink, which I've replaced with balsamic vinegar for the photo!
