Produced in the mid-20th century, this apothecary/chemist desiccator is a "Scheibler" pattern with very thick glass walls. Lid and body are etched with maker's mark. I have a few more identical NOS Moncrieff desiccators I'll be putting up in the next week or so, so if it's a full set for the kitchen you're after watch this space.
