McBride ceases fire after realizing his Winchester isn't doing much.
Colt Model 1903
Photographer Charlotte Cunningham (Sarah Douglas) carries a pearl-handled Colt Model 1903 in her handbag which is given to Bowen Tyler (Doug McClure) in the climax. He uses it to shoot several Nagas (Caprona natives who have advanced to a technological level resembling feudal Japan).

A bearded, older Bowen uses the gun against the pesky katana-wielding Nagas.
Hogan (Shane Rimmer) uses a forward-mounted Lewis gun shoot at a marauding pterodactyl as the expedition flies into Caprona. It has elements of both aircraft-mounted and non-aircraft-mounted Lewises.
Aircraft mounted Lewis Gun - .303
The Lewis gun has the wide barrel of the ground version...
...but the grip of the aircraft mounted version.
