Hi - Your pics aren't particularly clear on my monitor, but I'm not seeing any bright-cut engraving, and the design has a rather flat quality to it that makes me think it may be acid-etched rather than chased, and though hand chasing can certainly be done in low relief, don't believe that's the case here (I see the same look in other #1840 tea service pieces found online), the decorative band would have been applied. From what I can make out, your date mark does appear to be the 1887 fleur-de-lis, and while I can see a Japanese influence, to my eye, with its fluted lid and spout detail, and general look, appears fairly typical of the 1887 dating, with Aesthetic design transitioning out of fashion.

Welcome to the forums, HistoricalArchive. I'd be interesting in reading further information, can you cite your source for Gorham's use of Japanese silversmiths for their Japanesque silver? Can't recall reading or hearing of that before - though Gorham and other American companies produced quite a bit of silver in the Japanese style in the 1870s-80s, references credit it to their designers and craftsmen , and the only Japanese name I found on their roster of craftsmen emigrated to the US in 1902, was hired as a chaser in Dec., 1903.
