GRUMMAN S2F-1 FACTORY DISPLAY MODEL - 1950s These were used by Grumman to promote the sale of their sub hunter series of aircraft. VERY RARE ! ! "1:40 scale Grumman Tracker made by Topping. The S2F-1 was redesignated as a S-2 in 1961. This large model has a 20 1/2" wingspan. The clear base reads "S2F-1 Sub-Killer" with Grumman logo." You probably will not see another one like this again. This is NOT a Philippine mahogany model like you see all over the net. This was actually comissioned by Grumman in an effort to promote the sale of this aircraft. See web link provided. Excellent condition with some very minor scuffs. cash only first come first served. please email or call as I do not text. Thank You
