early Pyrex tray, clear glass oven proof kitchenware, depression glass vintage

Vintage clear glass tray / plate with a good early Pyrex mark at the center. This is 1930s, I think?

The tray measures 11" across the handles and 9 1/4" in diameter at the inside of the tray rim. There's a little scratching from use, and a straw mark raised mold mark to the surface left from manufacture, but there's no chips or cracks.
