Yes, it's a cut down version of the 1993 (4?) and 2001 GI Joe Headquarters. It lacks the gatling gun/missile launcher, the base that holds that gun and slides under the fortress and it lacks the larger of the two platforms on the tower. But it's colors are awesome! Dark Purple and Black.
TJ's Toys here in the US still has them mint in box for $30.00 if you're interested!
