This lovely large glass cloche was made by a company called Moncrieff, based in Perth, Scotland.
It is actually part of a science kit and was used at an electrical manufacturers.
The glass is in fantastic condition and has a hole in the top, used to attach other apparatus or a stopper, and there are a couple of small chips at the interior of the base, as shown.
It would look great on display with something inside, such as taxidermy, floral arrangement, objet d’art, etc
