Lord knows I don't know much... so i don't know if there ever was a Corsair with a bubble in the true sense like a P-51D, but the -1a was the 1st variation off the original with the bird cage and that was eliminated.
Ah but there was, the F2G "Super Corsair". The F2G was developed as the ultimate answer to the Kamikaze problem of the Corsair family, sporting a true teardrop bubble canopy and 28 cylinder P&W R-4360 3000 HP engine. The end of the war and the F8F brought it's development to an end after only 10 had been built. http://i274.photobucket.com/albums/jj241/jaepton/046F2G-2TaxiStarkes5X704-15-46Album.jpg
