Are these what I think they are and if so are they really made of
titanium (in which case I get the last laugh)?

Dunno about the big chunks, but that gear you're holding
came out of the differential (Chevy pick-up, 1954-60...)

;-)



That "gear" is a compressor rotor out of a cruise missile engine, quite
possibly a Tomahawk (Williams International F107 Turbofan). The other parts
are the engine cases and probably what is left of the turbine and the engine
accessories. The rotor is not Titanium. Most of the parts are a nickel steel
alloy.

The Allison 250 series have a compressor about the same size IIRC.
They are used extensively world-wide for helos.
It's been over 25 years though....
