Dear Mr. Gallagher,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the series titled Correspondence with Other Government Agencies, Army Commands and Units, and Schools, 1942 - 1945 in the Records of the Chemical Warfare Service (Record Group 175) that includes 12 file units relating to the Bushnell Project. For more information about these records, please contact the National Archives at College Park - Textual Reference (RDT2) at firstname.lastname@example.org.
Next, we located 43 series in Record Group 175 that include records about projects. In particular, you may want to review records located in the series titled Security-Classified Correspondence Relating to Research and Development Projects, Activities in Foreign Countries and Other Matters, 1942 - 1945 and Security-Classified Reports, Studies and Histories, 1942 - 1945. For more information about these records, please contact RDT2.
Also, the National Archives at St. Louis (RL-SL) has a list of who participated in the Bushnell Project. Please contact email@example.com for more information.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT2 & RL-SL. We apologize for this inconvenience and appreciate your understanding and patience.
In addition, we searched the Catalog for “Zephyrhills” and “Withlacoochee” in Record Group 175 but were unable to locate records relevant to this topic.
We hope this is helpful. Best of luck with your research!
