Dear Mr. Bowers,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located Motion Picture Films, ca. 1915 - ca. 1959 and Miscellaneous Films, 1913 - 1942 in the Records of the Extension Service (Record Group 33) that may include films from the 1920s. For more information about these records, please email the National Archives at College Park - Motion Pictures (RDSM) at firstname.lastname@example.org.
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 RDSM. We apologize for this inconvenience and appreciate your understanding and patience.
There also may be relevant materials at the National Agricultural Library and the Motion Picture, Broadcasting and Recorded Sound Division (MBRS) at the Library of Congress.
We hope this is helpful. Best of luck with your family research!
