Item No. "25148" [Vintage/Discontinued/Minor Dullness] YAMAHA Hex Rod Wrenches - 2 SETs. Green Label, L-shaped (some are hex wrenches), and others like orange and white labels. These are dedicated hex wrenches for rod adjustment. They are genuine YAMAHA products, but have been discontinued for several years. I am offering a treasure! Please forgive some dullness as they are from 1974. A small hex wrench of a different size is included.
