Grumman Gryphon-Cat. This is ScatCat, racing stablemate of the modified F8F RareBear. ScatCat is a heavily modified F7F Tigercat, with clipped wings, a smaller canopy, swept tail surfaces, and Rolls-Royce Griffons replacing the original R-2800 radials. Thanks to Kitnut and Perttime for the inspirations and suggestions...
