Me and my brother picked this piece up on eBay. The seller says its a 166.2 I just wanna make sure what it is. It measures about 4 1/8 tall but I can't get a good base measurement. due to the fact that the piece is very ovalized. By the long part of the oval it measure 3 and 3/4 in wide and the short side is 3 inches even

The piece has an inner skirt, no embossing, and its super crude. It looks fairly old.

Any help would be very much appreciated Justin
