Set Of 5 Vintage Cragar S/S Wheel Center Caps 4 w/Backing Plates

Description

I know a whole lotta nothing about car parts except I think they're cool and I buy them when I see them.
These are an estate sale find-dusty, dirty but in good, solid condition.
Three of them have a 2 under the plate, One has a 1 and the other says Japan with the number 0S0090.
They are all 3 1/4" across the back side to side.
Please look at all the pictures as part of the description and thanks for your interest.
