Could you please try if possible to id this incised monogram, letter A

It is difficult to tell from the images but it wouldn't surprise me if this was factory made rather than by an individual studio potter. The scratched mark looks more like a quality control mark rather than an individual potter's mark.

An image of the base of the handle might help.

Looks like the sort of clay and glaze used by Shelf Pottery and a couple of the Welsh potteries.

- A for Abaty Pottery, maybe? Although they usually use and ink stamp.

Another image showing the handle.

Thanks for that but it doesn't sway me either way. However, I would still be very surprised if the A is to identify the maker(s) to the public.
