The original 1/72 transforming VF-1 kits were done by Imai, later acquired and reissued a couple times by Bandai. I have a VF-1J Max Type from Imai and VF-1D, VF-1J Millia, and three VF-1As from Bandai. I’m not sure under which owner they were marketed through Revell. I should have a couple of those Revell kits somewhere, but I’ll be honest, I didn’t take good care of them as I preferred the Japanese kits.
Arii made 1/100 transforming VF-1 kits. I have one that was issued by Revell in the Robotech Changers series. The Revell instructions say “MACROSS, Tatsunoko Production MOLDED BY ARII, JAPAN” on the front page. Interestingly, it’s Roy’s VF-1S in the correct scheme, labeled as “VF-1S Battloid.” Revell didn’t market the 1/100 kits in funky paint schemes like the 1/72 kits.
