My grandfather who passed away way before my mom's memory served in Ww2. Recently when cleaning out the basement I saved his badges before throwing them out. Problem is that my mom said he worked as a resupply man in the European theatre for the US army air force, but the badges I found was a 9th fighter division and a mechanics trade badge and a American flag with a white boarder(none of which are resupply). Any information would be helpful because I've spent days searching government records and nothings matching up.
NOTE: The division badge is a red 9 in a yellow circle with silver wings and the army star with a red circle. The specialty badge is a blue triangle with a yellow cog. And the US flag is a normal flag with white boarder(but it could have been yellow and lost it's color). These badges were in a rough environment. A wet basement sitting for at least 40 years on the ground. I found them while scooping up the moldy dirt mess and saved them along with my uncle's air force badges.
