1940's Glass Measuring Jar Chopper Yellow Lid Turquoise Knob Stainless Blades

1940's GLASS MEASURING JAR / CHOPPER YELLOW TIN LID AQUA KNOB STAINLESS BLADES Wooden stopper included. Jar has measurements on the side. Two of the blades appear to be missing. I believe it is supposed to have 4 blades on the chopper. The spring may need to be replaced to be usable, the chopper moves up and down, but the spring slides down inside the lid, so it doesn't spring back up automatically. Still, makes a cute display piece. The colors are gorgeous.
