lot vintage US military insignia shoulder patches / badges

Lot of about 13 assorted embroidered insignia patches. Three of these are US Navy rank and service branch patches that had the tips cut so that the third stripes could be folded under before sewing the patch onto the jacket or jumper.

We think that most of these are 1950s or earlier because of the bright colors of the patches. They have some wear and the flaming sword patch (bottom left corner in the first photo) has severe fading and bleeding to the colors.
