The blue glass in the iron sleeve is Spanish as far as I know, and was made in the 1980s. It comes in a large range of decanters, shot glasses, table votives etc. Not sure who made these specifically - but I suspect it may be Lafiore production.
Wiktor Berndt items have a very high quality, and you'll immediately recognise the quality if you handle one. Sleeves are high quality copper - not crudely made iron.
