The Split is a 1968 crime movie directed by Gordon Flemyng and based on the novel The Seventh by Donald E. Westlake (under the pen name Richard Stark). A seasoned criminal McClain (Jim Brown) gathers a gang and successfully robs the Los Angeles Coliseum in the day of a great football game. The loot is hidden in the apartments of McClain's ex-wife Ellie, but when next day McClain returns to take the money and divide them among the gang, he finds Ellie dead and the cash stolen.
The following weapons were used in the film The Split:
Smith & Wesson Military & Police
Smith & Wesson Military & Police revolvers with 3" barrels are carried by security guards in Los Angeles Coliseum.
Smith & Wesson Model 27
Dave Negli's (Donald Sutherland) personal firearm is a Smith & Wesson Model 27. During the shootout in Gladys' bathroom McClain (Jim Brown) seases Negli's revolver and uses it in subsequent scenes. There are two different revolvers that has different shape of the front sight. The revolver that is used by Negli during his fist encounter with McClain and the one that is used by McClain in the final scene appears to be a pre-war Registered Magnum while Negli's revolver in the heist scene is a Model 27.
Smith & Wesson Model 36
Smith & Wesson Model 36 revolvers are McClain's (Jim Brown) backup weapon and Det. Walter Brill's (Gene Hackman) service sidearm. Bert Clinger (Ernest Borgnine) and Marty Gough (Warren Oates) are seen with snub nose revolvers that also appear to be Model 36.
All five robbers use Madsen M50 SMGs during the heist. Later a Madsen is used by Herb Sutro (James Whitmore). During the final shootout Clinger (Ernest Borgnine) and Kifka (Jack Klugman) arm themselves with Madsens.
Winchester Model 1897
During the final shootout Marty Gough (Warren Oates) carries a pump action shotgun. It is seen only partially and in heavy darkness but the general shape of the magazine tube allows to guess that it's a Winchester Model 1897 (or maybe Winchester Model 1912 but this is less credible).
Sporterized Arisaka Rifle
One more weapon, used by Dave Negli (Donald Sutherland) during the heist, is a bolt action rifle with sniper scope and sound suppressor. It appears to be a sporterized Arisaka, similar to the one used by Scorpio Killer (Andrew Robinson) in Dirty Harry.
