A professional colleague of mine has produced a 1/15 scale model of the X-15A-2, and can make a few more. The first part of the photos below show it sans stand; the second part shows it with a temporary stand. I understand that this particular model is spoken for, and will have a stainless steel stand. I imagine the production run will be rather small, considering the size and level of detail involved. The price he’s asking is $4,750 plus shipping.

Some detials: the drop tanks are held on by rare earth magnets, the front tank tube opening on the body has a little hinge that you can close after droping the tanks. The ventral fin is removable, held on with magnets, the horizontals are positionable.
And, yes, I’m quite jealous.
