Vintage barbie what number?

I bought this barbie. I don't know what number she is. I'm guessing she is a later #4 or #5. Her markings on the bottom reads Barbie above that in a circle (R) then below the barbie pats. pend.(c)MCMLVIII by mattel Inc

I was told the mattel on the later fours some had (r) and a solid body is that true? She has a solid body. She is in very condition.

I have a attached a picture. If you can tell me what number she is it would be so helpful.



Thanks, Kelley

Hi Kelley -
Grab your doll & check the Vintage Barbie Ponytail Comparison Guide and you should be able to tell which one she is.
