Interesting question...

...pre war R51 will have an "S" stamped on the ring gear cover...R51/2 will not have the "S" but is otherwise the same as pre-war...R51/3 will have a groove in the spring tower casting to provide better access to the 2 o'clock ring cover nut...of course the '54-'56 final drive will be much larger to accommodate the full hub wheel hub...I'm not certain, but the font used on the ratio numbers may be smaller on the pre-war final drives...
