My guess is that the 'Thou God' was made at the Albion Pottery, but perhaps after 1864, which would explain why it doesn't carry the G&A impress. I have still no reason to doubt the Scott attribution for the 'Victoria and Albert Yacht'. One last note of interest is that in taking the 'May Peace and Plenty' plaque off the wall again to measure it, I noticed that the Albion impress on the reverse doesn't have the G&A initials in the centre. So perhaps it too was made after, or slightly before, 1864.
I can't imagine I will squeeze in another blog post this week, so Merry Christmas, and thanks again to everyone who has contributed to MSTP in 2011.
