Vintage Gundam Diecast Raw Metal Japanese Robot 4" 1970's RARE **FLAW**

Vintage Gundam Diecast Raw Metal Japanese Robot 4" 1970's RARE **FLAW**. I don't know much about this piece, but believe it to be a Gundam metal figure. The front of the helmet is supposed to have two metal pieces coming out of it, but one has broken off, so there is only one - please see the pictures. Besides the piece that has fallen off and is missing, there are no other issues that I can find. I believe this to be a rare piece.
