I dug my old SS 'guard out and also had a look at some pictures of 916 'guards.
The two types do not look all that different to me.?
The difference is in the mounting bolt holes. I hope you can see what is going on with the bolt holes in the picture of the SS 'guard on top of my 916 type forks.
The SS 'guard will go straight onto your forks with no messing where as you will have to jig somthing up to make one fit from a 916.
My 'guard is a bit scruffy now but some of that blue paint of yours will transform it.
Is it derived from the blue on the early 900SS..?
PM me if you are interested.
The nasty looking split is just a crack in the paint, lifting and not a split in the 'guard.
