What does it go in? Sometimes you can get military equipment at DRMO sales if you have one you can reach. Maybe get in touch with turbine manifactures, Allied signal, turbo mach, Air Research ect, ect... Alot of times they will donate older engines or discontinued engines to schools. Another source at times is NASA. How you go about getting ahold of them(NASA) I don't know but have been in a school in AZ that NASA had donated some engines to. Hope this helps.
