thanks so much, Laura, that's very helpful
i usually end up buying the barbini lighters (i just seem to be most attracted to his stuff) so, it's nice to have something different.
Pip and Frank, it's also very easy to replace old lighter inserts with new ones so, that's one way to know the lighter itself has never been lit (to say nothing of the glass holder)... i've found, anyway, that most people who collect tobacciana (is that a real word or just an ebayism?) don't care about the working order of collectible lighters (unless it's not an insert at all and, rather part of the lighter or the insert is somehow otherwise bonded to the unit). new lighter inserts are cheap and pretty uniform as far as size.
thanks to everyone for responding
p.s. i'm pretty sure i've seen some basic bud vases with lighter inserts shoved into their tops and being sold as glass lighters... funny, eh?
