I only have one Saxon helmet, but this looks fine to me. The colors are reversed on mine because it's a Pioneer helmet (silver star, gold crest) but the front and back of the star look to be manufactured in the same way. My crest is a little different. My helmet is a private purchase so the crown is voided and the details are slightly more sharp. Mine is held on with screws instead of loops, but all that aside, I would not have an issue with this Wappen.
Here's mine for reference:
The Wappen is not too clear, but you can use it to judge size, etc.
