Jim,
Was sent your way by a kind email from Marion today. I may be of some help. My 9th AFA references in my library have the 876th AEAB arrived USAAF Station 424 at Sole Commom, Berks by 7.43, first unit assigned to 9th EC, carried out mainly maintenance of airfields, France Belgium and Germany.
Found another reference to them at Normandy on D+6 involved in patching together temporary strips for glider recovery. Last photo on my website article, Rescue at Remagen shows pilot Bud Berry of the 439th TCG doing a glider snatch recovering gliders at Normandy.
Contact for their reunion association (don't know how current this is)
876th Airborne Engr Bn (Aviation)
Mr. Elwood F Fahrenholtz 610-696-4384
1201 Greenhill Rd
West Chester, PA 19380-4010
Suggest you also contact the decsendent organization the 876th Engineer Battalion through their website for current association contacts. As the 440th TCG Association maintains contact with the 440th Airlift Wing, you may find a similar relationship between the WWII 876th and the present day unit.
Sincerely,
Randy Hils
