The dish in Chris’s opening post doesn’t ring a bell with me at all.
I agree with Paul that a ‘genuine’ British registered design number 304012 would have been registered in August 1897, but the number is not listed among those in the usual glass design registration references. The absence of the ‘Rd’ prefixing the number and the unfamiliarity of the design makes me suspect too that the dish is possibly American or continental European.
As to the pieces in reply #4 - not too bad a haul!
In addition to the Stuart piece:
The frosted flower boat appears to be RD 268883, registered by Jane Webb & Joseph Hammond &c. acting as executors for the late Joseph Webb on 19 Dec 1872 – Parcel 3. Not common, and quite an important piece of Black Country glass history as it was produced at the Coalbourn Hill Glass Works, Wordsley (now the site of the Ruskin centre), one of the very few glassworks in the area involved in mass production of pressed glass.
The white vitro-porcelain vase is Sowerby RD 299424, registered on 27 March 1876 – Parcel 13, Sowerby pattern number 1154˝ (because the sides are flared, otherwise it would be pattern 1154).
The pink bowl (which I think is probably a salt) is Davidson RD 413701 registered on 14 July 1903.
It has been a long time since I hunted for glassware at car boot sales, but even charity shops in this area (the Welsh Marches) seem to provide quite slim pickings. Most of the rarities I show now on the GMB and/or the GMB RD database have been with the kind permission of eBay sellers (many being sold for quite modest prices).
I am glad that the GMB RD database is proving to be a useful reference source, and am gratified that my contributions are appreciated – thank you.
Fred.
