I had the thought that if we compared lots of plaques with this transfer, we might be able to get an idea of the age of the worn plaque above. For instance, if there were pink plaques with the 'Dixon Co' impress and Wesleys with missing noses, it might imply that production of the black and yellow plaques continued into the 1850s or even into the 1860s. But that's not what I found.
All the plaques below could come from the same transfer plate. Look at the spacing of the letters in the second detail. In particular the space around the letter 'o' in 'Methodist' and 'Society'. That is consistent through all the transfers below. The contrast of the details has been turned up in PhotoShop, so it is the first image that best shows the relative strengths of the transfers. I have ordered them from strong to weak as best I can.
The interesting find for me is that there appears to have been no overlap between the production of black & yellow and pink lustre plaques. For this transfer at least.
