It appears to be a variation of the Cross Pattee: http://knightstemplarvault.com/templar-cross/

I thought I posted this last night, but it for some reason didn't work. I thought it was similar to a World War II Order of the German Eagle medal of some kind, but you seem to already have figured it out! I just thought I'd re post what I thought, since it didn't work last night!
