There were actually quite a few differences between the Merlin 66 and Merlin 63. Most of them were related to the supercharger, but overall the Merlin 66 had less horsepower as well, about 1500hp vs 1700 for the Merlin 63 in the F.IX.
Which is why when you read stories about mixed squadrons of F.IXs, LF.IXs and LF.XVIs, the earlier IXs had to throttle back so the others could keep up with them.
I can write up some more data when I get home. I have a specific book on the aero engines used by the various airforces in WW2. That said, i guess the individual differences between the engines such as the size of the impeller blades or compression ratios don't really matter aside from the horsepower ratings, altitude ratings, and full throttle height.

What sort of images do you need? Specific areas or generic shots? If specific, which areas?
I'm still struggling to find a scanner, but if you can let me know what you need I can certainly give you descriptions of the areas. Even if I can't scan the images in, I should be able to get some decent shots of the net with some targeted searching.
