Brady and all, I still think it is a S&W "Hand Ejector" in .455. I went to the safe, and the pistol in the photo and the round in the Tommy's hand do not look my Victory model in .38/200 (aka .38S&W) in my hand, both are too small. My S&W 1917 looks right, as does the ammo 1942 dated Brit for my wife's Webley.
The .455 case is almost the same length as the .38, and the round in the photo looks too "squat" for the .38, but does look like the .455.
I vote for the book being wrong.
Or a small Brit.
