RARE Amberina Castor Set

Here is an extremely rare castor set in Amberina. Some say this was perhaps produced by Mt Washington but I don't know that for sure. The set consists of a Salt & Pepper, an Oil Bottle and two Mustard jars. These sets are rarely seen and sold! One set of 4 bottles sold for over 2100.00 a few years back! This is my favorite castor set!
These bottles have a combination of cut glass elements to them as well as an etched pattern.
I've posted better pictures of this set to truly appreciate this set!
