Thanks Sue
I found that one in a thrift shop in Switzerland a week or two before everything closed down due to Covid-19.
It's not signed and but for the label I wouldn't have known what it is (even though Riihimäen being one of the few companies I'm starting to know and recognize at lest a little bit......) haven't had much luck finding anything similar on the web, until last week when I found this forum and a link to Designlasi.com that identifies it as a "Rulla 1319" apparently by Tamara Aladin and probably from the 1970s.
I havent taken a "lone" picutre yet but I can give the measurements if interested:
It's approx. 240mm in hight
the base is approx. 94mm in diameter and the top 115mm
(so it's bigger than the one shown in the link but based on the google picture search it comes in 3 (?) different sizes and in clear, amber and "my" blue)
The weight is 1.084kg
I really like the rolled in top
