perhaps I'm being a tad picky, but believe that the vast majority of 'rummers/goblets' that are discussed here are free blown and made in parts, as is standard practice with hand blown/made drinking glasses.
My opinion is that - for this thread - it could be of some benefit if the subject heading includes the word 'pressed' - just a thought.

As to whether we follow the wording of the factory drawing and call this pair goblets, as opposed to rummers, is debatable - but since it's true that the majority of rummer shapes will fit into ......... ovoid, ogee, bucket, cylinder and barrel, and possess a capstan or knopped stem - then this pair would probably not be described as rummers.
Although there probably shouldn't be confusion, there can on occasions appear to be a lack of easy distinction between goblet and rummer shapes, and this is compounded by those many folk who refer to all largish cup shaped bowls as 'rummers' .......... these people probably don't have Tim Mills book - a very good read and worth every penny........... a must if you have an interest in C19 rummers, whether pub/tavern or the posh end of the spectrum.
Fred - unfortunately, believe you're right, and it seems we are still in the dark over this non-Rd. 198277 piece. I've been through all of the National Archive pix I have for tumblers/rummers/goblets during the diamond period of 1842 - 1884, and I've not been able to find this single teardrop pattern
