1970s Vintage Gold Plated Twisted Hoop Earrings

These were my moms They are from 1970s . These are not hollow. They have some weight to them. They are thick twisted hoop earrings w a rope featured in the middle. I believe they are brass w gold plating No loss of color on the hoops minor loss on the piercing part as shown in pictures I believe I have replacement backs Not 100% sure They look like the Milor earrings but no stamping that I can see
