24 hours later and there may be a better approach. My trip last night to a local locksmith (yeah, a real local guy) unveiled the lock series number under a layer of corrosion and accumulation on the nose of paddle end of the housing. Less than 30 seconds in a database that he had and a key was being cut. Another 2 minutes and I had 4 keys for $20 and was on my way.

A relic barely alive. Gentlemen, we can rebuild her. We have the technology. We have the capability to build the world's next bionic legend. Better than she was before. Better, stronger, faster.
