Wear says something about a piece - but absence of wear is not so telling. It could have been sitting at the back of the cabinet for the last 50 years, what do you know. Which may have been the case with this example. First it looks as if there is a mismatch between body and stopper. The stopper looks like a modern mass produced (like Empoli, Oberglas or even Taiwan) which is outside its comfort zone. If they are a match, then it is likely from the sixties but more likely seven- or eighties. But all is hypothetical - there is no way you'll ever recoup your investment on a chipped piece. <bond voice on> Really, woman, get a grip on yourself! <bond voice off>
