I've got one of these (pic is not mine, but exactly the same condition and factory paintjob)
It's an absolute monster at about 6"x4". For comparison, the figure pictured(not included) is about 30mm tall.
20 bucks plus actual shipping* via paypal.
I also have the dethroller front and support arms leftover from an earlier project with another one of these models.
They can be yours for 9 bucks shipped.
*Actuall shipping means I'll get a shipping quote and then refund you the difference if there's more than a buck difference in the actual shipping costs.
