The fragments of cabin were handed down to the descendants of Quentin Roosevelt's former landlady in Issoudun, central France where the young pilot was based.
They were "without much visual value but very moving," said Laurent Mirouze of Aiolfi Partners who have put a 250 euro ($335) opening price tag on them.
Several US museums have shown interest.
"We don't know how (the landlady) got hold of the fragments and if it was friends of Quentin Roosevelt or soldiers who gave them to her," Mirouze added.
Quentin Roosevelt was shot down aged 20 over eastern France on Bastille Day, July 14, 1918.
