vintage seed cleaning screens, stacking wood & metal sieves for separating seeds

vintage set of seed saver's stacking wood and metal screens for separating and cleaning, sifting and winnowing small seeds. A must have seed saving tool! We've also seen them being used as herb rubbing screens for harvesting dried herbs.

There are 5 screens as well a tray with a solid metal bottom for catching the sifted seeds. They measure 9" square over the wood frames and about 7 3/4" square over the metal screens. They have different sizes of screening, 3 of them are marked for clover seeds and 2 are marked for timothy grass. However, we're think they'd work as well for many other small seeds.
