Can't help with either of Bryn's goblet vases, unfortunately, despite going through a lot of pix, but thought this thread might be suitable place to add some closely related items from other factories, which might be of interest. Not intended as a definitive resume, but just some thoughts and details that come mostly from Kew, and which are pieces most closely resembling the vases here - however, if considered out of place, feel free to move to wherever.

Pix 1 and 2 are the well known J.J. & T. Derbyshire Rd. 242570 (21.06.1870) shown in Manley (also on Neil's site where you can see images of all three panels). Quite an irony that Manley speaks of acquiring his from the Snowdonia area of N. Wales, which coincidentally is where I found this one. He also says that during the 1950's he saw these not uncommonly in that part of Wales - although doubtless they're not so now. This one is mine (at least for a while) so no need to credit anyone else for the pic.
Pic 3 is the same Derbyshire brothers - Rd. 242570 (21.06.1870), and is stated in the Archives to be an 'ornamental design for breakfast set' - so presumably this ornamentation appears on other items for the table. Sorry the pic is a bit bent.
Pic 4 - again J.J. & T. Derbyshire Rd. 251012 (15.03.1871) which appears as another example stating 'ornamental design' - so whether this refers to the shape and moulded pattern, or just the pattern, I don't know.
Pic 5 - Registered by Ker Webb - No. 263362 (13.06.1872) - and is the well know 'pair' of ornamental goblet vases depicting male and female busts. It's worth looking at Neil's site to see these in the flesh and to read his comments regarding possible attribution of the sitters.
Pic 6 - back to J.J. & T. Derbyshire with Rd. 267727 (06.11.1872) - described as a 'Roman Vase' (?) and appears in the Board of Trade image without any decoration, so possibly the most plain of this type of object.
There are other goblet vases incorporating hands, fish etc., but I've avoided those and stuck to the simple pedestal form which are closest to the two posted here.
Believe Ed. Moore also produced similar vases - Thompson attributes some green examples in her book and comments that these are shown in the Moore factory pattern book, and says that they date to c. 1880, although unfortunately it appears that Ed. Moore didn't register any designs between 1868 and 1886 - so outside the lozenge period, and means at present I don't have any pix. Am sure however that someone here must have one of these vases. I don't have an example to show.
If someone can let me have the Rd. Nos. for the Sowerby examples which are mentioned earlier in this thread, I'll re-check the Kew pix and see if I can find anything.
Hope I have above details correct - but if there are errors or whatever, please feel free to comment and put matters right - or anything else anyone may wish to add.
