Back in 1969 I was a minor participant in the recovery of B-29/P2B-1S "Fertile Myrtle". She flew the airshow circuit for several years before being retired due to corrosion in the tail and a lack of title to her engines (along with the four extras).
She is now owned by Kermit Weeks. Her nose was in his museum in Florida where it was seriously damaged when the museum collapsed in Hurricane Andrew. The rest of her is in storage.
"Myrtle" was the mother ship for the Douglas D-558.2 Skyrocket. When she returned to flying it took a B-50 center fuselage to replace the highly modified original.
I don't know if anyone here is interested in the story. Let me know and I'll jot down a few paragraphs.
