Stelvia Glass Jug

Found this at a local cat charity shop. It was cheap but wasn't sure I wanted it at first but after a through clean (mould on the outside and all sorts of hard to move muck on the inside) it has come up well and really love it.
Comes from the maker Stelvia from the Empoli region in Italy. They have been making glass since the 50s and I think this would be an earlier piece judging by the hollow base, something that is more like they made them earlier in the century. I see a lot on the net with solid bases unlike this one.
310mm high and 160mm at it's widest
