The fore/aft chord on all later masts were close to the class max of 135mm=5.31 inches. The IYE 110 masts had a for/aft chord of ll0mm. To my uncalibrated eye it looks to be a later section that should accept prebend loads without problem. If the spreaders are adjustable raking them back more will induce more prebend with less tension on the diamonds. The prebend needed is dependent on crew weight and luff curve. My current spreader rake is ~32mm=1.25", but when I sailed with my wife we used 50mm=2"
