So, further to my previous; the police have always stated that a Smith & Wesson .357 Magnum revolver was used due to the nature of the two recovered bullets. If they are basing that on the bullets alone then they cannot say definitively that that particular type of firearm was used.
The .357 Magnum cartridge is identical to the .38 Special cartridge except for the former is slightly longer. This is done primarily in order that the former cannot be chambered in a revolver designed for the latter as .357 is loaded to significantly higher pressures. Pressures that lots of older .38 revolvers, which might date back to 1899, will not be able to safely handle. The extra length also provides for a greater internal volume so that more propellant can be used.

The particular 158 grain Winchester-Western metal piercing bullets which were recovered from the scene have been loaded into both .357 Mag and .38 Special ammunition. I have some of the latter which I'll post pics of in due course. In one of the old news reports in the documentary they were described as "armour piercing" which is not correct - they were intended to penetrate car doors and windscreens more effectively than other rounds.
This being the case, I don't know how the police arrived at a definitive decision of them being fired from a .357 weapon without having a cartridge case (which revolvers don't expel) or them having other reasons which haven't been elaborated on.
So, it could be
either a .357 or a .38 revolver which was used. Personally, I would err towards being a .357 based on the witness interviews; one guy (a taxi driver, I think) described it as an extremely loud bang which tends to suggest a .357.
In addition to the above, the police have stated very definitely that the gun was a revolver made by Smith & Wesson. They called in every licensed .357 made by S&W for testing but never identified any gun as being the murder weapon. My question would be - how do they know that it was
definitely made by S&W? Now, it's possible that they can identify the particular rifling pattern on the bullets as being one used only by S&W but I've seen nothing to back that up.
I seriously wonder whether it was actually a gun made by S&W at all. It's only my suspicion but I'm concerned that something may have been mixed up here; as is described on the above Wiki link, the full name of the cartridge is ".357
Smith and Wesson Magnum" because it was developed by them and a few other guys in the 1930's. Is it possible that the investigators got mixed up and assumed that only S&W make guns for this round so were only looking for S&W guns, I wonder? The cartridge has been chambered by Colt, Ruger, Dan Wesson, Starr, Astra and Taurus to name just a few. There will be dozens of others. Unless they have info to confirm it as being an S&W I'll remain skeptical.
As a point of interest, I'm loosely connected to this (very loosely); my ex, who was 5 at the time, lived about two streets away and told me years ago that she remembers hearing the sirens and commotion going on at the time.
