This one was solved by Mr. Bob McBride of Arkansas. He is interested in building a replica someday, so if you have any information, send me an email, and I will get it to Bob. Go to the “Mysteries” page and select “Mystery # 3” link and you will find what the helicopter pictured below has to with a Curtiss Wright Junior.
This mystery comes from Jim Bradshaw and concerns a relative of his, Texaco Oil and Shawnee Oklahoma. Jim is trying to identify the aircraft in the photograph which was flown by his relative. Select “Mysteries” to the left and then “Mystery 4” and see if you can help us.
