1930s vintage depression era kitchen glassware, McKee Range-tec heat proof sauce pan

1930s vintage McKee glass saucepan, Range-Tec textured clear heat proof glassware - an early competitor of Pyrex, or Fire-King. Hard to find these days!

This is a one quart saucepan, about 6" in diameter x 2 1/2" deep. No chips or cracks, this is nice and clean showing little wear or use.
