Vintage Heavy Glass Condiment or Sauce Bowl with Base Plate and Spoon

Vintage thick glass condiment or sauce bowl with matching plate and glass spoon. In very good vintage condition with no chips,, cracks or other defects. Not branded. I couldn't find anything like it anywhere on line so I have no manufacture details. It came from my mother in law's estate 12 years ago and I'm not sure how long she had it. I'm listing it as vintage although it could be antique, just not sure. Bowl measures approximately 6 inches in diameter, plate measure approximately 7 1/2 inches in diameter and the spoon measures approximately 6 inches long (or just shy of).
