Unfortunately, Teign Valley Glass paperweights have not yet made it into mainstream collector discussions at club and book level.
[What a specialised bunch some of us are, with our distinctions between "collector weights" and "gift items", even though many of the so-called "gift items" are probably collected by many!]
So without a confirmed similar example it will be hard to say whether the green-and-blue 'blobbed' flower weight is TVG or not. However, I do have a small vase by TVG which has a simple, but effective, 'blobbed' ruby (darkish cranberry) coating. The initials are very difficult to see, let alone photograph, so I won't try. But the "G" is different to both of those shown by Leni and Jean. I suspect there were several different folk signing the TVG initials over the years.
I have had my small vase (which could easily be mistaken for Wedgwood Glass) for over 10 years, so 'blobbed' work at TVG could well have been in fashion in the 80s / 90s.
Perhaps a query should be sent to the folks who would know:
