For those in western Oregon, Madras Maiden, from the Erickson Collection is in Eugene through Saturday, March 11th. Free walk throughs after 2:30 PM. Eugene airport at Atlantic Aviation.
I've seen her over at Madras, and is well worth the time if you want pics for a B17 build. Was formerly "Chucky" when they had her over in Tillamook.
Is on a 9 month tour of the United States, so other parts of the country may have achance as well. Part of the Liberty Foundation tour. I haven't done a search, but you may be able to find the schedule from them.
**EDIT** Went to Liberty Foundation site, and she will be in OR & CA during March/April. They also have a pretty good photo collection of various 17's.
