Both MITW and TW Vaders are almost impossible to tell apart,
both of these CoO share the same features, and the only way to tell them apart is the CoO stamp on the back of the leg.
I have an AFA TW only Vader with a grading summary from AFA, that says it is a TW only CoO.
With out this AFA document i would consider it to be a MITW CoO.
The AFA label on the case is exactlly the same as a MITW AFA graded Vader, both the MITW and TW will have TW on the AFA label.
A while back, i wanted to try my luck, and bought a reasonablly priced Vader TW AFA80 on the label, from ebay but without the AFA document saying it was a TW only.
When i received it, i cracked the case open, the figure had a MITW CoO.
A graded TW only CoO Vader, should have the afa document to accompany it.
