Hans Diedrich Schmidt was not a goldsmith but a merchant who mostly dealt with Fabrics and wine etc. He had a big department store in Pernau. The engraving might be his but that is all. I don't either think it is Brackman because then the assay marks should be Russian ones and they aren't. Unfortunately the maker's mark is partly destroyed/invisible. Only the last letter a B is visible. I would bet on Fredrich Ernst Behrens punching FEB or FE/B in 1780-1803 in Pernau. Another alternative is Andreas Berg 1712-1723 because the end of the frame looks rather rounded, but...hardly...?
An engraving does not tell the date/year of manufacturing. It can be done at any time by anybody. The official marks are crucial, not the engravings.
