Plaques attributed to Sheriff Hill and Robert Maling

Please read my previous blog post first. Thanks to the high resolution photo (third below) on Boldon Auctions website, I think we can prove that the Sheriff Hill attributed plaques (first two plaques below), and the Robert Maling attributed plaques (third plaque below), share transfers from the same copper plate.  Note the 'd' in 'death' in particular.

The problem is that Robert Maling (mark used 1830–40) and Jackson & Patterson (mark used 1830–1845), were in operation at the same time.  If anyone out there has any clues to the links between the two potteries please get in touch.

P.S.

I should mention that the orange plaques, like the one below, attributed to Ball's Deptford Pottery come from different transfer plates. The punctuation of the verse is different (N.B. no full stop after 'GOD').  I've transcribed the differences on the Other scripture verses page.  Another puzzle...  Balls were renowned for recycling other factories' transfers.  Yet I don't know of this version of the transfer appearing anywhere else.
