Some of these images appear on Garrison Pottery items, but also on items from Scott's. For a long while I assumed that the copper plate had passed from Garrison to Scott's, when the Dixon partnership was disbanded in 1865 (see here). But it's now clear there were two copper plates, with near identical designs.
The first column of images below shows the Scott versions, for comparison with the copper plate in the second column, and the Dixon versions in the third. The 'Scott' Agamemnon (and the Garibaldi) is taken from a bowl, so the transfer appears distorted as it is applied to a curved surface. The 'Manchester Unity' on the bottom left is taken from a mug. All of the other transfers details come from photos of plaques. Click on the images to enlarge them, and to move between them.
I did find a small dink on the copper plate that shows in the Scott transfers, but not on the Dixon transfer. Take a look at the details from the Gauntlet Clipper below. There is a dark, horizontal scratch that appears in the centre of the copper plate detail, and also on the Scott detail (left). However, there's no sign of it on the Dixon transfer (right).
