I don't have any black ones, but here's a vehicle mode size compatison for anyone interested. From top to bottom: Smallest Transforming Transformers Optimus Prime, THS-02
, G1 Optimus Prime, and MP-4.
And just as a point of interest... Not to be a pain in the arse, but I really hate thread titles like this. I shouldn't have to click on a thread in order to figure out what it is a thread about. Couldn't you have used a more discriptive title such as, "Yes! Finally got my hands on a THS-02B!"
That being said, congrats on your find.
