Alright, stupid question time!

I found the original "protection plan" book and in it are the numbers for the trans, engine, axle, etc. How can I identify what these are in modern english?

For instance, axle no. is P61011. What does this translate into? I am trying to determine axle ratios at the moment and figured this would contain it. Internet research shows nothing thus far.
