Here we have a vintage 1970’s Buick Steering wheel with horn button.  It is dark green 3 spoke.  Part # 9752507-1.  15” diameter.  This steering wheel is in outstanding cosmetic condition.  One possible issue is -shown in picture 8 -Im not sure if that is the turn signal switch canceling actuator and it is worn or if that is how this is manufactured.  Other than that, this is a beautiful steering wheel.  See pics.
