This is a pair of vintage egg beaters. The first is by Maynard and has a black knob and handle marked "Maynard" on each side. One side of the handle has some deep scratches and definitely shows some wear. The other side of the handle, however, looks great. It is stamped "Made in USA" on the wheel.
The second egg beater features a cream colored plastic knob and handle. It is marked "Worlbeater" "Los Angeles" on the wheel. Both egg beaters are in perfect working condition.
