I was just making an observation/comment in regard to someone else's post.

In General

From my quick & limited research, as far as I can tell there is very little visual difference between the GSP Hellcat and the "Prototype" with the 4 blade prop other than the propellor obviously. The XF6F-6 "prototype"was a futher development of already in-service Hellcat airframes that they upgraded to a more powerful engine with a 4 blade prop. In this particular case I guess the label "prototype" is a little misleading in that they used an existing proven airframe and "upgraded" the engine. Splitting hairs here probably.
