I thought I'd check items in my own collection and see if I could find a match, and where better to start than the Mariner's Compass, which has always been a favourite transfer.
The transfer on the Seaham jug is easily distinguishable from the transfer found on plaques attributed to Newbottle and Moore's (a Newbottle plaque shown on the right below). Compare the two details, each from the item above. N.B. the transfer on the jug (left) is applied to a curved surface, so there are distortions of perspective, but even so, it's clear that the transfers come from different copper plates. The shading of the fur on the lion's cheek is running in a different direction. The tufts of grass in the foreground are different.
Look at the lower right quadrant of the shield (third row below). The centre jug and the bowl have a dark line through the diagonal white band that doesn't appear on the first. Also look at the lower left points of the star in the centre of the compass (bottom row). The centre jug and the bowl have a scratch coming off the point at SSW, but again the first doesn't.
