RoG has been related to Revell of America on and off throughout it's history. I read in a magazine that it was formed in 1956, roughly a decade after Revell of America. They issue more kits than the parent company does, and they (naturally) have a more European slant to kit subjects. Some of their kits are also issued in Revell of America boxes, and some Revell of America kits are issued in RoG boxes as well. I don't know if I have any of either, but I've read about them.
