Ruck, "Constancy of the Velocity of Light in Vacuum", Spectroscopy Letters 5(12), 455-461 (1972). Abstract (full): "Recently a series of papers1-15 have been published tending to discredit Einstein's principle on the constancy of the velocity of light in vacuum and to renew theories on the propagation of light abandoned long ago. Subsequently we rediscuss some of the arguments and inconsistencies presented in Refs. 1-15." Notes: this is a published reply in the same journal that carried Wallace's four papers; the "1-15" suggests a run of c+v papers in Spectroscopy Letters 1969-1971 (Wallace, Rapier and probably others). Full text paywalled; not read. It is the nearest thing found to a contemporaneous published rebuttal, and bears on claim 6 (Wallace's account of hostile reaction and Robinson ceasing publication in 1979) and on claim 1.
