The Bridges at Toko-Ri
The following weapons were used in the film The Bridges at Toko-Ri:
While LT Harry Brubaker (William Holden) is trapped behind enemy lines, Mike Forney (Mickey Rooney) and Nestor Gamidge (Earl Holliman) go to rescue him, armed with Korean War standard M1 Carbine Rifles. Forney later gives the rifle to Brubaker, who remarks that being a jet pilot, not a soldier, he wouldn't know how to use it. A WWII Walnut Stock variant is seen held by soldiers on the aircraft carrier.
Smith & Wesson Model 10
After crashing his plane in enemy territory, Brubaker takes a Smith & Wesson Model 10 revolver to defend himself against enemies before Forney and Gimadge arrive.
Two North Korean soldiers fire at Brubaker and Forey with a Soviet made Degtyaryov DP-27 drum-fed machine gun.
Mosin Nagant M91/30 Rifles
Enemy soldiers are seen armed with what appears to be Mosin Nagant M91/30 rifles in the finale. The M91/30 would be correct for Communist/North Korean troops. In the second photo, it is apparent that the rifle has a slanted metal box magazine and a straight bolt, both being features of the Mosin Nagant series of rifles.
In addition to the Mosin Nagant rifles, one of the North Korean soldiers is armed with an unidentified nickel revolver, possibly a Webley variant.
