for whatever reason I'm minus pix of the G. G. de Luca pomade obelisk - neither am I able to see any pix of the blue marble Vitro-Porcelain piece.
I can understand this one and the blue example being absent since neither appear to have been Registered, so are naturally absent form TNA records.
But why the Luca picture is absent from my photos for 1877 is a mystery - always possible I've overlooked taking a photograph, but always possible the original factory image has been removed from the Kew records. Perhaps the next person who visits TNA at Kew might check 315269 to see if the original image is present - the Board of Trade reference is Representations book 43/62 which covers most of that decade.
This is what passes for humour at this late hour - I can't imagine anyone actually visiting TNA in west London
Look forward to additional pix Mike, and while you're at it you might decipher the hieroglyphics for us.

It's a shame that Jenny Thompson didn't elaborate a tad on why she suggested Ed. Moore - in view of the fact that it's V-P, plus the colour, there's a real temptation to think of Sowerby.
