Query: author:"AG Kelly" Sagnac OR relativity OR "speed of light" (page 1 of 2 read; page 2 not read). Result: positive.

Found [web] (Kelly's own publications as indexed)

"A New Theory on the Behaviour of Light" (1996; cited by 7). PDF at forum.aethercosmology.com (saved; see aethercosmology note).
"Synchronisation of Clock-Stations and the Sagnac Effect", in Open Questions in Relativistic Physics (ed. F. Selleri, Apeiron, 1998), cited by 2. PDF hosted in a ResearchGate upload of the proceedings (https://www.researchgate.net/profile/Sotirios-Baskoutas/publication/253119316_On_Superluminal_Velocities/links/0f3175375db45cad31000000/On-Superluminal-Velocities.pdf#page=38). Not downloaded (ResearchGate). Snippet: the CCIR report "tacitly accepts that it is not a Special Relativity or a General Relativity effect".
"The Sagnac Effect and Uniform Motion" (aethercosmology PDF, indexed as 2011): the project document (see aethercosmology note).
"Faraday's Final Riddle: Does the Field Rotate with a Magnet?" (1998; cited by 11), at emmanuelavionics.org (saved).
"A potential source of some dark matter", Physics Essays (2003) (Gale record GALE|A226047443).
Citations only: "The Sagnac Effect" (HDS Energy); "GPS and the One-Way Speed of Light" (2009, a localization proceedings, posthumous); "The Location of the Missing Dark Matter"; "Sagnac effect contradicts special relativity", Infinite Energy (2001), cited by 5; "The Sagnac Effect and the GPS synchronization of clock-stations", International Meeting "Galileo Back in Italy", Bologna (1999), cited by 9.
From the first Google search: a ResearchGate paper cites "A. G. Kelly, Phys. Essays 13, 616 (2000)".

Claims 1-3 and 5: the Infinite Energy 2001 paper ("Sagnac effect contradicts special relativity") and the Bologna 1999 / Selleri 1998 papers are earlier or parallel statements of the same argument; they would help date the undated project paper and show how it evolved.
