Queries (results summarised; the sites opened from them have their own notes):
1. "Bryan G. Wallace" "Radar testing of the relative velocity of light in space" — positive. Hits: GSJ PDF of the 1969 paper; Taylor & Francis (Spectroscopy Letters 2(12), 361-367, received 12 Nov [1969]); Semantic Scholar; sciliterature.50webs.com PDF (SpecLetters1969-p361-367.pdf); GSJ author page; Natural Philosophy Wiki bio; viXra "Is the light velocity constant?" citing Wallace; ResearchGate (1971 paper); Math-Net.Ru entry for Shapiro "Radar observations of the planets", UFN 99:2 (1969), whose citing list includes Wallace 1969 [web] https://www.mathnet.ru/eng/ufn11250
2. "Wallace" "Physics Essays" 1990 "3" 94 OR "Galilean Electrodynamics" "Bryan Wallace" — partial. Did not find Wallace's 1990 Physics Essays 3(1), 94 or Galilean Electrodynamics 1(2), 23 papers online. Secondary mentions only: ResearchGate/viXra "The Aether" (2019/2020) calls him "American radio astronomer, d.1997" (a characterisation that differs from other sources); "Galileo Was Wrong" (Sungenis, geocentrist book, archive.org/dokumen.pub) relays Wallace's Shapiro claim; a Zhihu (Chinese) column discusses him.
3. Horedt Ruck "Constancy of the Velocity of Light in Vacuum" Spectroscopy Letters 1972 — positive (see tandfonline note).
4. Rapier "A recent application of detection and estimation practices in radio and radar astronomy" — positive: Pascal M. Rapier, Burns and Roe, Inc., Oradell NJ; Spectroscopy Letters 4(9), 303-311 (1971); abstract begins "Very-long-baseline-interferometry tests of the exploding Quasar 3C-279 show conclusively the presence of two components" [web] tandfonline snippet. Cited in sciepub "Replacement of Einstein's Relativity Theory with a New One" and Semantic Scholar "Astronomical phenomena disprove Einstein's special relativity".
5. "Fourth Texas Symposium on Relativistic Astrophysics" Shapiro "Observational tests" Annals New York Academy discussion Wallace — negative for the discussion transcript. Found only I. D. Novikov, "The Fourth 'Texas' Symposium on Relativistic Astrophysics", Soviet Astronomy (ADS lists Dec 1967) — the date conflicts with Wallace's "Dallas 1968"; unresolved (needs the proceedings volume).
6. Tolchelnikova Wallace radar Venus "c+v" OR "Bryan Wallace" Leningrad 1989 conference space time — positive: NPA wiki page "1st International Conference on Problems in Space and Time" ("Bryan Wallace and Bob Fritzius were privileged guests at an otherwise exclusively Russian conference"); Friebe-hosted Farce Ch.5 with Leningrad photo caption.
7. Tolchelnikova "Doppler observations of Venus" Galilean Electrodynamics — positive: S. A. Tolchelnikova-Murri, Galilean Electrodynamics 4(1), 3-6 (1993); antidogma.ru (Artekha, "Foundations of physics (critical view)") bibliography; ritz-btr.narod.ru Russian article (see note); Stephan J. G. Gift paper on Scribd cites it.
8. "Bryan Wallace" physicist "St. Petersburg" 1997 obituary OR "Eckerd" — negative (only unrelated namesakes, e.g. a sea-turtle biologist Bryan Wallace).
