While going through an abandoned trailer at the cape, I found the album in a trash barrel.
I also have the complete set of progress photos which document the conversion of ML-1 to MLP-3, used to launch the shuttles. Negatives, too.
I attemped to turn those all over to NASA, but they wouldn't accept them. So I simply took them home for safekeeping.
If, at any point, you want to recover your storage space, you might try the National Archives or the Manuscript Division (Archives) of the Library of Congress.
You did the right thing!
