Royal manticore navy

in the extremely good but at this point extremely long military sci-fi series by David Weber the main character- honor Harrington- moves through many adventures and many many battles,from junior captain to ranking Adm. in the Royal manticore space navy-this is my version of their uniform patch it's not perfect but it's pretty close.
You should really read these books.( word of warning- 'word of God' is that no character is safe- many MANY fascinating people have died in the course of these books. well one characters untouchable- and it's NOT the star of the series- apparently the author's wife really likes someone and won't let him kill them off.)
// update they've announced that an honor Harrington movie is in the works for release in 2016-as soon as I get a better quality picture I'll try and redo the design. // added a fourth pin
with a double pentagram ring on the outside, no letters

as usual any comments positive or negative greatly appreciated
how am I going to kn
