Duralast brake shoes

Is that a Russian service manual ?
I just put in the proper perspective so it would match up. Still looks wonky at yellow circle. Do the arcs line up, like did you get a 9 and a 10? Here is another reference pic: Another observation...is the cocked strut seated in the piston or is it hung up on the top edge?
