Hi. I am new to the forum. I recently picked up a collection of 1977 figures and one has me stumped. It is a Darth Vader, unfortunately with his head broken off, but the inside of his cape is red. I have not been able to find anything online about this. It is a Canadian version stamped GMFGI 1977. This was an innocent childhood collection so I am 99m percent certain that it is original to the figure. Any help would be appreciated.
