Does anyone truly know what Mig-25 Kits were made & who were the mfg's

I just got a hold of one with no instructions.. not even sure who made the kit. Did
Knights of the Air , World Engineering any others????

I'm going too finish this kit about mid summer but i'm pretty much guessing. here
could really use a Hand or any help on locating and old Instruction Manual with prints.
would be a great help..
