Possible uses of keys in description titles are suggestions only.  Actual uses are left to buyers’ expertise and research. All vintage keys are used and may have wear or discoloration commensurate with age and use.  When present and observed, we do notate any rust presence in titles and descriptions.  We never use other sellers’ photos or stock photos, so the items pictured are the items you will receive.  We have a sixty-day money back free return policy so you can purchase with confidence.
