Daniel grinned.
“You sound paranoid.”
“I worked for Thomas Keene.”
They photographed the frame.
Serial plate.
Welds.
Hydraulic modifications.
Then Daniel used a small grinder to remove the later weld without cutting deeply into the original structure.
Sparks filled the shop.
It took almost forty minutes.
Behind the plate was a cavity.
Inside sat a rectangular metal case sealed in deteriorated rubber.
Michael whispered:
“Jesus.”
Daniel pulled it free.
The case was heavier than expected.
No lock.
Two latches.
He looked at his father.
Michael nodded.
“Open it.”
Inside were engineering drawings wrapped in plastic.
Several notebooks.
Test sheets.
Photographs.
A stack of floppy disks.
A small data-storage cartridge.
And a Polaroid showing three young men beside XP-2.
Michael was one.
Thomas Keene stood in the middle.
A third man, Walter Greene, stood on the other side.
Daniel held the photograph beside his father’s face.
“You had hair.”
Michael took it.
“Get out.”
Daniel laughed.
Then Michael found a notebook.
The first page carried Thomas Keene’s handwriting.
XP-2 FIELD TEST LOG.
Michael flipped through.
Flow rates.
Temperatures.
Pressure cycles.
Fuel consumption.
Load conditions.
Handwritten corrections.
Then the final pages.
The handwriting became hurried.
April 17.
Primary recovery loop stable.
May 2.
Fuel reduction continues between 11.8% and 15.4% depending on operating cycle.
May 7.
Greene wants demonstration canceled.
Investors pushing asset sale.
May 9.
If program disappears, drawings stay with machine.
Then one final line.
The machine works.
We simply ran out of money before anyone important was willing to believe it.
Daniel read it twice.
Then looked at his father.
Michael stared at the words as if thirty years had folded in half.
For the next week, nothing else in the shop mattered as much.
That created a problem.
Bills still existed.
Customers still needed work.
The one functioning lift still functioned only if nobody looked at it too aggressively.
Michael refused to let Daniel turn the prototype into an obsession.
“We work customer jobs first.”
“Then XP-2.”
Daniel hated the rule.
He followed it.
During the day, they repaired tractors, pumps, pickup trucks, and a skid steer.
At night, they worked on the prototype.
The engine was a six-cylinder industrial diesel that had not run in at least fourteen years.
Daniel drained what remained of the fuel.
It smelled like varnish.
They removed injectors.
Changed filters.
Cleaned the tank.
Inspected the cylinders with a borescope.
Two showed surface corrosion but no catastrophic scoring.
The starter was seized.
They rebuilt it.
The alternator wiring had been chewed by rodents.
Daniel replaced sections carefully.
The hydraulic system took longer.
The main pump could probably be saved.
Several hoses could not.
Seals had dried.
The custom recovery circuit was worse because many components had no obvious modern replacement.
That was where the notebooks mattered.
Keene had documented everything.
Pressures.
Thread sizes.
Substitutions.
Daniel spent hours cross-referencing components online and calling industrial hydraulic suppliers.
Most people hung up after hearing the machine was a thirty-year-old prototype.
One supplier in Nebraska became interested enough to help.
A retired engineer there remembered Prairie Dynamics.
“Thought all that stuff got scrapped.”
“So did everybody.”
“Send me pictures.”
