Cloth belts like used in a browning 1919 ?
The browning design pulls the round back out of the belt, then lowers the round under the "feedtray" as it feeds it forward into the chamber.
The 42 is a push through design where the belts hold 3/4 of the round ,open on the bottom, and the bolt pushes the round (forward only) into the chamber.
The 42 has a simpler, I feel a better design.
"good , bad, .....I'm the man with the gun."
Its amazing anything works right around here with a bunch of
over-age juvenile delinquents running the place.
