This 'Ace' company it's not the Ukranian but Korean. Maybe is this tooling the origin for the Revell and Kangnam ones? It would be interesting to see a pic of the sprues.

The Revell Vigilante kit box said "Made in Korea" and I've read that it was made by Ace, along with the Yak-38 Froger, and Su-25 Frogfoot 1:72 kits.

Yeah this is the Korean company. I picked this kit up back in the 80's when it first came out. I started it in the 90's and plan to finish it this year. It is a good kit, simple, but good.
