Please help. Are S & L KCs in marked 935 silver (including the loop) with or without the 3.00 pm shown in photo, post-war production?

I have rather a lot riding on this.

My understanding is that the S&L Knight's Cross without the die flaw and marked "935" or "935" with incuse "4" are original pre-1945 production. Most collectors consider S&L Crosses with the die flaw post war.
