Leads for review

1. The inventor's own work (Lindemann; and Gray as the source inventor)

• Gray's foreign patents: US 3,890,548 has family members CA 1030600 A and JP S50-74712 A [web: https://patents.google.com/patent/US3890548A/en]. Their texts may carry claims or figures not in the US text. Bears on claim 1 and the "narrower point" (what the patent itself claims).
• An unlisted Gray application: "Regenerative Energy Recovery System, e.g., for Electromagnetic Propulsion" (10 April 1980; "Unidentified British Application Number"). Its abstract describes discharging a capacitor through an inductive load, with a diode letting the inductive current go on to charge a battery [web: https://www.rexresearch.com/evgray/1gray.htm]. US 4,661,747 also shows a priority date of 1983-12-16, earlier than the 1984 application named in the book [web: Google Patents list]. Bears on claim 1: Gray's own description of the mechanism between the 1975 motor and the 1986 tube is recovery of inductive back-e.m.f. energy, which is the explanation Lindemann sets aside.
• Lindemann's earlier and later work: A History of Free Energy Discoveries (1986), video Tesla's Longitudinal Electricity (1988), lecture 12 Sep 2000 Irvine CA (ExtraOrdinary Technology Apr 2003), Radiant Energy & Its Role in Our Free Energy Future (2006), the Bedini SG handbooks, a 1987 Lindemann-Dollard video [web: https://wiki.naturalphilosophy.org/index.php?title=Peter_A_Lindemann; https://teslauniverse.com/nikola-tesla/articles/radiant-energy-unraveling-nikola-teslas-greatest-secret]. Bears on claims 1-2 (how the radiant-energy thesis developed).
• Author background (interested party): D.Sc. honoris causa in Complementary Medicine (Open International University of Alternative Medicine, Colombo, 1999-2000); Vice President of Borderland Sciences Research Foundation 1987-1999, which published his 1994-95 articles; co-founder of Clear Tech, Inc. (2000) [web: naturalphilosophy wiki]. Bears on all claims (stake and credentials of the author).

2. Supporting information by others

• Crosby Research Institute test, as reported by the Tattler (1 July 1973): J. A. Maize, for Pan World Enterprises (Japan), ran the motor into a 10 hp dynamometer at 1,100 rpm ("7,460 watts") on batteries "only capable of 5,454 watts per hour", and is quoted: "total battery power consumed is only 26.8 watts per hour" [web: https://www.rexresearch.com/evgray/1gray.htm]. This is the only numerical test claim on record. It comes from a tabloid advocate, about a test commissioned by an investor with a stake, and no Crosby document has been found yet. Bears on claim 2 (gain) and claim 5.
• Endorsements: Dr. Norm Chalfin and Dr. Gene Wester (Caltech, as stated by the Tattler/NewsReal) "publicly endorsed Gray's motor"; Chalfin: energy is "used only during a small fraction of a millisecond" and the rest is "returned to an accessory battery" [web: rexresearch]. Bears on claims 1-2. Note that Chalfin's description is the partial-recovery mechanism in the patent.
• Anonymous witness (KeelyNet, 2000): an "overunity demonstration that ran continuously from batteries for 12 hours", with batteries ending "with more power than they had when the test started". Six motors located in 2000 [web: https://frienergi.alternativkanalen.com/Graymotor.htm]. Bears on claim 2 and on what happened to the hardware.
• Evidence against, kept in the record: Donald Cronin (TRW Systems) watched a test about mid-1974: "It ran for about 10 seconds and then everything blew". A Japanese team "packed it all up and went back to Japan" (AP 1975, via rexresearch). This is documented in one published wire story; no second source found yet. Bears on claims 1-2 and 5, and agrees with Lindemann's own failed copy.

3. Closely related work

• A present-day replication community: groups.io EVGRAY forum (topics 2019-2024 "EV Gray CST", "Capacitor energy anomaly"); Reddit r/plasma_pi "Modern Cold Electricity" (circuit said to be "improved and simplified" by Lindemann) [web: Google results, not visited]. Bears on claim 1 (replications of the tube circuit).
• KeelyNet 2000 lists related US patents: McDonald (25 Apr 1978), Gifford (10 Oct 1995), Gossler (7 May 1996) [web: KeelyNet mirror]. Not checked.

4. The historical record

• The prosecution, from the DA's side (AP wire, 7 July 1975): prototype, plans and books seized July 1974; in May 1975 "one count of conspiracy to commit grand theft, eight counts of grand theft, and three counts of a securities violation"; about 800 shareholders since 1971; DA investigators invested and "later got it back"; the DA found it "hard to find investors willing to press charges" [web: https://www.rexresearch.com/evgray/1gray.htm]. Bears on claim 5: it confirms the raid and the charges independently, and the counts are heavier than Lindemann's "grand theft ... dropped" and "two minor SEC violations". The outcome is still to be found in LA Superior Court records. The "SEC violations" may be the California securities counts.
• Death record: a VA-created Find a Grave memorial and a FamilySearch tree give 8 Jan 1925 - 20 April 1990, died Sparks, Washoe County, NV; buried Riverside National Cemetery (plot 27-1479; veteran) [web: https://www.findagrave.com/memorial/3813396/edwin-vincent-gray; https://ancestors.familysearch.org/en/LY5P-7C9/edwin-vincent-gray-1925-1990]. Lindemann gives April 1989 at his Sparks shop "under mysterious circumstances". KeelyNet 2000 gives April 1993 in a Riverside trailer, with conflicting police accounts and no autopsy record found. Bears on claim 5. The year in both advocate accounts conflicts with the government-derived record. Cause and circumstances are still open: obtain the Nevada death certificate (Washoe County) and any April 1990 obituary.
• What became of the patents: US 4,595,975 lapsed for non-payment of fees on 17 June 1990, about two months after the death [web: https://patents.google.com/patent/US4595975A/en]. KeelyNet's informant says "Western States", "an oil drilling company", owns the rights to the Gray patents, with Zetech as an earlier holder. Bears on claim 5 and the "absence of evidence" question (absorption by another company versus abandonment). USPTO assignment records would decide it.
