Bayonet Bonanza

[Peter Laidler]

I'm just guessing now, with an idea based on nothing more than my limited experience with military specs. F-10. Maybe - just maybe....., the spec stated that all sharp edges must be removed and the hole diameters must be clean and blemish free. You'd expect that. After all, we, at the sharp end had a go/no-go gauge to test fit fit and ovality. Additionally, the sharp edges would be removed otherwise the poor souls would be shredding their hands to ribbons on the sharp edges. JUST as your photo shows. Gauged hole and edges linished(?) clean albeit roughly!
