By the looks of the cars in the background, looks like mid 1960's.
This aircraft is photographed in a different scheme in an early 80's Aeronews photo and was the subject of a search.. Stolen from Tonopah Nv in May it was found in Merced in September, in better condition. In the photo she was owned by Earl Dodge of Anchorage Ak, and then by Mike Coutches until 1993. Now in santa fe NM [Christopher Gruys] but I havent seen this one in many years..interestingly she is a consecutive survivor, she followed Jeff Michaels, N98582 down the line, (976) Still reg N5448V 44-74977
