Vintage Antique Detonator

Your bidding on a Vintage CC Blasting Machine or Detonator. Purchased at an auction for an old excavating company. I'm not sure of the age exactly. The is a crack that has been repaired on one of the side panels. I have been able to generate a spark but not everytime. The Handle rises and falls easily. Has a brass plaque and thumb screws on the top along with a leather handle. Seems to be completely original. Similar item have sold for hundreds of dollars.
