J.Roberts made two scale kits, the Martin AM-1 Mauler and the Chance-Vought F4U Corsair. Consolidated had a Grumman TBF Avenger and a Ryan FG-1 Darkshark. Sterling had the Grumman AF-1 Guardian, but that came around in the mid 60's. These were the only scale made for carrier event kits. The Japanese made quite a variety of scale kits and the one you saw very well could have been one of them or of course scratch built. Mike
