Complete logs. There was a significant event, probably a groundloop in 1979 with a 337 to show the repairs. Since then, the occasional patch or reskin of an elevator or horizontal stabilizer can be seen though the logs. Not much damage in the last 30 years. Early life was in Alaska. later life in Colorado. Currently in Northern California at Placerville airport. A good late “E” model Skywagon. The E models are the pre-1973’s and they do not have the camber cuff wing. They have a once piece cabin top and the wings are flush rivetted. It is argued that the E’s were the best built of the 185 years. They are 12 volt planes and have the earlier style panel.
