Funny enough you may get a decent price for it as all the other bits could be made by a collector, it is usually the cast crankcase that most don't like to carve from solid.
Would certainly help if you knew the actual engine. Maybe ask on Model Engine Maker Forum as there are a lot more aero engine enthusiasts there or drop an e-mail to Adrain via his site
I have also altered the thread title which may get a few more who know their engines looking in.
