For your consideration, here is a Vintage Rustic Rusty Metal Egg Beater, with Twisted Stem.  No manufacturer name on it.  It does not want to turn.  It locks up after turning it a bit.  More of a decorative type item.  It has wear, corrosion spots and some white spots on it.  It is 9 3/4 inches long.  I think it would display nicely.  Item pictured is the actual item up for sale and comes from a non-smoking household.  (324.881L-.10kx)
