That is a correct spring set for a WW2 metal cot/barracks bunk.
Check this blueprint
The date is a little hard to see but I make it to be 1943. As you see, there were two spring sets approved for use. Spring Fabric Type I (top example) is the more familiar type with the wire pieces with loops on each end interwoven in a rectangle configuration held at each end by springs. Spring Fabric Type II (bottom example) was a long length of wire (like aircraft cable today) which was run back and forth between the springs at each end then held in that diamond configuration by metal clips. I have examples of both types but I see no comfort difference between the two - maybe the choice of producing either type depended on what components were available. Raw materials shortages because of the war. I believe you have the Type II Spring Fabric.
BTW - the information for the bunk itself should be stamped on one end of the bunk cross piece facing out.
