I’m not aware of Lattimer duplicating the overall shot with dummies set up in the same relative positions as JFK and JBC as Alex Krstic (the Australian test) did on the Unsolved History episode. Lattimer duplicated several elements of the SBT but if he did an overall reconstruction, I’d like to see his results if you can tell me where I could find it.
Lattimer used animal tissue to simulate Kennedy's neck, a rib cage to simulate Connally's torso, and radius bones wrapped in simulated forearms to simulate Connally's forearm. But nothing was used to simulate Connally's back or chest muscles.
Lattimer said four out of his 20 bullets struck all three objects. A picture of one of the test bullets shows it was split at the nose in several places and was markedly deformed, much more deformed than CE 399. When Stewart Galanor asked Lattimer, in a filmed interview, if he could examine the bullets that struck all three simulation objects, Lattimer said he had thrown them away (
Cover-Up, New York: Kestrel Books, 1998, pp. 41-42).
A detailed analysis of Lattimer's research can be found in chapter 6 of British physiologist Russell Kent's 2022 book
JFK Medical Betrayal: Where the Evidence Lies.
Lattimer discussed his SBT test in two articles that I know of:
"The Kennedy-Connally Single Bullet Theory: A Feasibility Study,"
International Surgery, 50:6, 1968, pp. 524-532.
"Observations Based on A Review of the Autopsy Photographs, X-Rays, and Related Materials of the Late President John F. Kennedy,"
Resident and Staff Physician, May 1972, pp. 34-64.
I'm guessing you may have already read John Hunt's seminal article
"Breakability: CE-399 and the Diminishing Velocity Theory," which, among other things, discusses the Australian SBT test.
I would also recommend an article written by our very own Benjamin Cole:
"The Death of the Tumbling Magic-Bullet Theory: the Governor’s Shirt, the President’s Shirt, and the Overlooked Dr. Robert Shaw."I would further recommend
chapter 11 in Pat Speer's online book A New Perspective on the John F. Kennedy Assassination. Speer spends considerable time talking about Lattimer's SBT claims.
