Additional Information:

Colt’s large-frame revolvers, like the Anaconda, were engineered with reinforced frames and lock-up systems to handle high-pressure cartridges. The crane lock screw is essential to this system, anchoring the swing-out cylinder arm with exacting tolerances. Factory screws are increasingly difficult to source, and using original components like this ensures proper mechanical integrity and collector-grade authenticity.
