Hey,
That's an original MK Blue Angel. The company still kits the BA and they are available from the far east - cost: about $240 shipped to the USA. The original box top showed 2 kits: the Blue Angel and the Fuji. I have an original Fuji .60 kit - same box top.
I think Model Airplane News may have published the plans, they published plans for many pattern planes back in the 70's (Atlas, Arrow, Super Sicroly, Curare, Compensator, Deception, etc.).
MK kits are great!!

PS - You can still get the Curare, which MK is currently kitting (and the Magic and Skymaster - original kits). I can give you the web site if you're interested:
