This is an original 1937-38 Chevy RIGHT LOWER Front Door Hinge.  Pretty good condition, some pitting, spots of pitting in areas and some normal wear-see photos.  It is not stuck, moves good.  Threads look useable but a few may need some chasing-see photos.  GM Book shows this fits all '37-38 Chevy Closed car models.  May also fit Convertible-not sure.  Please check my other auctions.
