What engine are these fan blades from? I bought these from a metal scrapper and paid about $30.00 total figuring they're worth more than that in cool factor. Problem is they aren't nearly as cool if I can't figure out what engine (and hopefully aircraft) they come from. All I know is the compressor blade is titanium and the turbine blade has a high nickel content. So here I am hoping someone has an idea.

Also what might cause the wear patterns at the tip of the turbine blade? I appears like it may be cracked and then repaired. I cant imagine they would repair damage that extensive. 

I cant find any pitting on the edges of either blade, leading me to believe neither blade was ever used, is my thinking correct?

Turbine Blade
The turbine blade (part number 1475M35P01) is from the High Pressure Turbine (HPT) a CFM56-3 according to this ATSB report on performance testing of the engine. The report contains several images of blades which look similar to your photos.

Compressor blade
A search on locatory.com for the part number (B778503) lists the description as C-3 suggesting it could be a Stage 3 compressor blade. This would fit with the high aspect ratio of your blade.
