Your badge is different than mine. Both of my Bonanza's are 1969 with the kidney bean wheels. The "BONANZA" on both of my badges are raised or embossed. Also the rivet holes on mine are closer to the center than yours. Maybe they changed in 1969 along with the introduction of the kidney bean wheels. Also my badges say "San Jose Calif.,USA. Yours does not say "USA". I have heard stories that the badges used were all in a big bin and were just grabbed off of the top. The badges on the bottom of the barrel so to say may have been there for years because they just kept grabbing the badges on top of the barrel.
