Murano for sure, but maker? (candlesticks)

I think these candlesticks (there is another, just photographed one for the ID) were made in Murano for sure. but i'm not a glass expert person, so can anyone narrow it down further for me? my internet research has led me to Salviati as they're appear to have used this ruby red glass with gold/aventurine inclusions quite a lot. Also, the grape type prunts seem characteristic of their wares. Can anyone confirm or deny for me please.

It is true Salviati used ruby glass and prunts, but so did others. I have seen recent, i.e. still in production, somewhat similar by at least 2 others. Wish I could be more specific.
