The actual range of Britannia is quite vast, as were Waverley and Spiderweb. I saw a picture in 'Mirror for Chance
' and wished I'd photocopied it now, however I am hoping to get a scan which will be much better quality.
The Deluxe range were essentially just coloured versions. I think these have a band of colour around the middle so the pattern looks different to make room for this, but is still identifiable.
I've now found my notes on the Britannia 'De Luxe
' range (not sure of spelling but that's what was written down):
De Luxe range from 1950 used colour (Moss Green, Blue, Amethyst and Ivory inserts
As to what the "inserts" are, I imagine this could either mean the 'cut' decoration or a separate panel of colour like the Waverley example: something at the back of my mind says the latter because I'm sure I've seen an example at some time. If it does have a separate panel it should look very impressive, I reckon.
