Old style front had apostrophe after "CHIEF". Also note that chief aides had same format and color regardless of level of chief. BC aides and DIV aides have had the same format
Appearance. If it looks too good to be old and used, it is not old and used. Brand new looking front pieces are brand new. You can also ask the seller what the background is. Authentic fronts often have a story that is passed with it. Although many FFs have fronts from different companies they served in, it is too bad that dealers who get old helmets with fronts from retirees usually separate old fronts from old helmets to make more money with 2 sales.How do you tell if a helmet or helmet front is authentic and not a fake or reproduction? I'm starting to build my collection but would like to know some pointers on what to look for.
