MG38: Colt's Interwar Water-Cooled Machine Gun
The Colt MG38, based on the Browning Model 1917, featured significant design improvements like self-contained recoil springs and a higher rate of fire (up to 850 RPM) achieved by lightening the bolt. The 'B' designation in MG38B specifically indicated models sold with spade grips, differentiating them from earlier or standard configurations.
