Might be Morley, but I doubt it. His first mark was not entered until 1775 and was in partnership with G. Baskerville. Also his mark had a pellet between the T and M not the clear star in this example. The ghost mark could be an I making it I*M for Jacob Marsh ca. 1763. Dave

I think yours is an unregistered mark attributed to either Jacob Marsh or John Moore. They were both active in this period; Marsh having an item dated 1763 and Moore one dated 1767. Marsh is the more probable one as his item was a mug. I hope this helps. Dave

Hi-there was a maker registered in 1834 whose mark is similar to yours being WJ period between by the name of Walter Jordan. He had a second similar, though not illustrated, mark which might well have included a pellet rather than a period. Perhaps you could research this maker further. Good hunting.

Thanks for the added info. GH is possibly for Harrison Bros. & Howson , a maker of table plate in Sheffield whose mark was entered in 1897. The piece used as a example in Jackson was made in 1902. Hope this helps.

Hi-Without a photo of the marks, identification would be iffy at best. Can you post one? Also, does the finial on the lid swing aside or is it hinged? If not, it is probably a coffee pot as chocolate pots would have this feature so that the stirrer could be inserted.

Hi-There are several makers with the mark TB, but a couple seem to fit the bill. One is Thomas Barker whose mark was entered about 1819. Another possibility is Thomas Ballam, entered1820. There are some others but they have a pellet between the letters. Hope this helps.
