Moore and Scott bowls and jugs often have similar lustre decoration. Impressed marks, usually on bowls, tell us with certainty where the items were potted, but not where they were decorated. From the 1860s, there appears to have been some division of labour, with Scott's, supplying Moore's with plain earthenware for decoration.
Decoration on these Moore items is typified by zig-zag rows of pink lustre, something like an ECG (electrocardiogram) trace during ventricular tachycardia. Ian Sharp has compared the zig zags to the letter 'M' for Moore. Scott's also used wave-like decoration, but the waves tend to be smoother, shorter, and more curvy. However, the first bowl below shows that Moore's also used curvy waves. So trying to identify wares based on lustre decoration is an imprecise science.

But... and it's a huge but ...we know what Scott-decorated jugs and bowls looked like in the 1860s, and they look very different from those decorated with ship transfers. The items with ship transfers, even if they're impressed Scott, have more in common with Moore bowls from the 1850s.
I think the confusion about attribution of the brown-bordered plaques has arisen because there are so many Scott-marked bowls with the ship transfers. Whereas, Moore appears to have made very few bowls and jugs during the 1860s. Perhaps decorating Scott jugs and bowls was enough, and Moore's focussed their energies on making plaques. Or perhaps Scott's made the plaques too, and all Moore's did during this period was decorate. But whoever did the potting, Moore seems to have more right of ownership of the brown-bordered plaques than Scott.
