Topic: Wine glasses engraved signature

[JOK]

I have three of these wine glasses which have hand engraved marks to the base. The marks read "model anno 1859" and then something like "HGi". I was wondering if anyone knows who made them. I am assuming they are studio glasses, but one has the shadow of a rectangular label near the top of the bowl which may or may not have been a factory sticker. The third glass has a slightly different monogram which looks like "HG" above "6".
Any information would be much appreciated.
