Jimmy Lowe's C-185?

Greetings,

I'm currently writing my memoirs which won't be complete without tales
about Jimmy Lowe,famed Alaskan bush pilot, skydiver and jump pilot. His
Cessna C-185 was always immaculate despite the hard usage he gave it, at
least in my limited experience. http://www.ntsb.gov/aviationquery/
brief.aspx?ev_id=20001213X25979 briefly describes his last flight in a
Helio Stallion.

My question is, can someone tell me please the registration number of his
C-185?
