Not what is referred to a suicide front end - that's what you call a single cross spring with a high or protruding center mount.
This is a Ford truck front axle, the grille gives you a clue as to the year - late 40's, early 50's. Mounts have been welded to the axle (batwings) for the 4 bars to bolt to, and mounts for the quarter elliptic springs and friction shocks. It seems to be a fairly well thought out setup, personally I would have trimmed off the old leaf spring mounts as well to clean up the appearance.
