I have 2, a January 1943 and a November 1943.
The Jan'43 manual is early enough that the Specific Engine Flight Chart still references "100 OCtANE (AMEND. #4)" which is the designation for US made AN-F-27 Amendment 4 100/125 grade fuel. It also talks about the 200 USgal ferry tank in the fuel system section.
The Nov'43 manual has some updated sections in it, I think from early-'44(?) but am not sure. An example is that it references the 'flat' 150 USgal drop tank in the fuel system section, and there is information on the water injection system for the P-47D-5-RE model.
