Unusual Scientific Tool Graduated Lucite Measures Case

Here's an unusual item that we believe to be a scientific tool possibly used to measure liquid displacement. Three similar lucite shapes each getting progressively larger are held in a leather cone shaped case. Each one is polished smooth and has a concave bottom and grooved channel in the top. When measuring them, I noticed that they magnify the numbers on my ruler if I look through them sideways. Total height of case is 4-1/8". The units measure:

  • 1-1/2" high x 1-9/16" at base and 1-3/8" at top - groove is 7/16" wide
  • 1-1/8" high x 1-1/4" at base and 1-1/8" at top - groove is 6/16" wide
  • 15/16" high x 1" at base and 7/8" at top - groove is 5/16" wide
They are in very good condition. The male end of the snap has come loose from the leather but stays in place when the lucite shapes are in the case. Outside snap surface has darkened in part. Purchased from an estate sale many years ago.
