Stella Randolph's files apparently do not contain any subsequent "contract" between the Whitehead family and William J. O'Dwyer. Further, no evidence can be found of an inventory of items as requested by the Whitehead family. So, precisely what constituted the totality of the "Whitehead memorabilia" is not known, although certain items are known to have been in the group described by the phrase "Whitehead memorabilia," such as the five Buffalo Public Library aeronautical books taken by Whitehead in November of 1897.
It now appears that a large portion of the "Whitehead memorabilia" - including the five books public library books - was given over to the Deutsche Flugpioniermuseum Gustav-Weißkopf in Leutershausen, Bavaria, Germany, on the 1974 trip made by O'Dwyer and Randolph, and referenced in the April 14, 1975 letter, above.
It's striking to consider that on the trip to Germany, material was "given" to the the Deutsche Flugpioniermuseum Gustav-Weißkopf - apparently without the consent of the remaining members of the Whitehead family, who owned it all (except for the five Buffalo Public Library books - still the library's property to this day).
It is, perhaps, even more remarkable that prior to and even after
the trip to Germany, Maj. O'Dwyer had still not yet made contact with the Whitehead family. Had he wanted to reach the Whitehead family, he could have easily done so through Stella Randolph. It appears as though Maj. O'Dwyer had little interest in contacting the Whitehead family, for whatever reason or reasons.
Stella Randolph, in stark contrast to O'Dwyer, was in close touch with the Whitehead family, and seems to have kept them informed at each step. However, there is no mention made to the Whitehead family - at least, none that can be found in the files which have been reviewed - of the agreement between Randolph and O'Dwyer dated March 10, 1964.
The end result was that the all or some of the "Whitehead memorabilia" seems to have been left in Germany at the Deutsche Flugpioniermuseum Gustav-Weißkopf in 1974, and the Whitehead family seems to have been left wondering why Major O'Dwyer and the Leutershausen museum honoring their family member had failed to get in contact with them.
A few thoughts about "Whitehead memorabilia" ending up in the Deutsche Flugpioniermuseum Gustav-Weißkopf… it's appropriate that Gustave Whitehead's birthplace have a museum in his memory, but the thought does come to mind as to whether or not the Whitehead family has seen any material gain, as they ought to have, from the fundraising and other revenue activities of the Deutsche Flugpioniermuseum Gustav-Weißkopf.
The Whitehead family apparently never gave up legal possession of Gustave Whitehead's "memorabilia," and under the terms of clause #3 of the March 10, 1964, agreement between Stella Randolph and Maj. O'Dwyer, "Any financial return from any use of the Whitehead memorabilia in any way will be shared equally with the Whitehead family."
