Working strictly off memory "C5OA" means the part was first engineered for
some mid or full size Ford around 1965.  The "1150" is the "Basic" number
that identifies what type of part it is, ie; hubcap, fender, fuel sender,
etc.  The "B" suffix denotes that this is the second variation of this
item.  That said could it read C5OA-1130-B?  This would make it a wire
wheel style hubcap with a three prong center spinner.  If so they are for
1965-66 Mustangs, again if memory serves me correctly.  It has been decades
since I worked in a Ford Dealership Parts Department and not quite as long
since I was heavily involved with classic Mustangs.  Do you have a photo
you could send of them to confirm?
