X-15 Model Collection

Those that love to model the X-15 you might like to know the types of kits out there. I have a few, and always looking to fill my collection. For now the Special Hobby 1/32 scale kits have my attention, and now looking for add-on such as pilots. Please excuse the quality of the images, taken with an old cell phone.

First up, the Airmodel 1/72 Vacuform kit. A very basic kit.	And to go with it a 1/72 adapter from Frank-Modellbau, all you need would be a B-52 to modify.
Then there is a resin 1/48 kit of the Delta Winged X-15. Still looking for who made it though, it has an entirely wrong engine.	Another resin 1/48 kit is by E.C.P. Phenix from France that has white metal parts as well. Not cheap.
I also have the normal injection kits like Monogram's 1/72 for the Young Astronaut, always a good starter kit and one to add detail to.	Or the original box for the Older Astronaut?
For those that are running out of room, a rare UPC HO scale.	Or the equally rare Starfix kit from Israel? in 1/125 scale with test boom.
Many remember of course the Revell in the odd 1/64 scale Limited Production X-15.	But then came along the Special Hobby 1/48 kits with better detail (more cost but fits with my Gemini and Mercury kits).
Special Hobby also had the white version with the dummy scramjet as well.	For the older collectible there is also the Aurora 1/50? scale also with a test boom.
