Don't mean to sidetrack the photo comparison, but had a little more to add regarding the alleged original autopsy of the body presumed to be JWJ.
Excerpts from " The Border Bandits ; An authentic and thrilling history of the noted outlaws, Jesse and Frank James, and their bands of highwaymen. Compiled from reliable sources only and containing the latest facts in regard to these desperate freebooters. Also full particulars of the assassination of Jesse James ". - by*J. W. Buel
* Buel was a Missouri newspaperman, with experience on St. Louis and Kansas City newspapers, and purported to be the reporter who received his information directly from one of the four doctors who performed the preliminary autopsy of Jesse Woodson James in 1882. ( Note: There was never an Official autopsy report made or recorded by those doctors ). He became a prolific Author and his books can be found in many internet archives.
REGARDING WHETHER OR NOT THERE WAS A CORONER'S INQUEST, AND LATER AN AUTOPSY, AFTER JESSE JAMES' ASSASSINATION ON APRIL 3, 1882:
( from "The Border Bandits," testimonies at the Coroner's Inquest given by Charley Ford, Robert Ford, Henry H. Craig: Police Commissioner of Kansas City, James R. Timberlake: Sheriff of Clay County, James Andrew "Dick" Liddil, James Finley: Deputy Marshal of St. Joseph, and Zerelda Samuel, pages 451-460 ):
" . . . on Monday morning of April 3d, between the hours of nine and ten o'clock, the long looked for opportunity sought by the Ford boys presented itself, and Jesse fell a corpse from the effects of a pistol ball fired by Robert Ford, the particulars of which are officially told at the coroner's inquest held in the St. Joseph Court House a few hours after the shooting. Charley Ford was the first witness examined. . . . She [Zerelda Samuel] then retired from the room, and the [coroner's] jury withdrew to make up its verdict. After remaining out for about fifteen minutes they returned again to the room with the following verdict:
'We, the jury, find the body before us to be that of Jesse James, and that the deceased came to his death by a pistol shot fired by Robert Ford.'"
( from pages 464-465 ):
". . . About three o'clock in the afternoon [on April 3, 1882] a special train from Kansas City brought to St. Joseph Sheriff Timberlake, Commissioner Craig, Mrs. Samuels and several other parties, relatives and acquaintances of Jesse, upon whose arrival the [coroner's] inquest was begun at the [St. Joseph] Court House, and testimony was taken as already given. After the inquest was concluded the body was turned over to Mrs. James, who permitted it to remain at the undertaker's exposed to public view until after an autopsy had been made by Drs. George C. Catlett, Jacob Geiger, Hoyt, and Coroner J. W. Hedden. The skull-cap was removed to permit a thorough exposure of the brain, which was found to be above the average; the bullet entered the occipital bone, immediately behind the right ear, and traversed the brain in a slightly upward direction until it lodged in, but broke through, the skull back of the left ear, being found at the junction of the anture. The brain and skull were dreadfully shattered, large pieces of bone having been driven through the wound, which lacerated the entire cerebellum.
