Dealer bulletins.
Parts diagrams.
Old seed company calendars.
The boy opened the first box.
Dust filled the air.
Nothing.
Second.
Tractor manuals.
Third.
Planter manuals.
His pulse quickened.
He carried the box downstairs.
His mother saw him.
“Homework?”
“Done.”
“Really done?”
He stopped.
“Mostly.”
She pointed toward the kitchen table.
“Really.”
Twenty-five minutes later, math complete, he returned to the manuals.
He spread them across the dining room floor.
His father sat in a chair reading the farm paper but was clearly watching.
The boy opened a faded green binder.
No.
Another.
Then a gray parts catalog from 1968.
On the cover was the symbol.
The same symbol cast into the 24-B plate.
The boy stopped breathing.
His father noticed.
“What?”
The boy held up the plate.
Then the catalog.
Same mark.
His father stood.
The manufacturer was not one of the giants.
It was a regional company called Midland Agricultural Works, once based in Illinois.
Midland had built mechanical planters from the late 1940s through the early 1970s.
The company merged with a larger manufacturer and eventually disappeared.
His grandfather's catalog showed dozens of seed plates.
Corn.
Soybean.
Sorghum.
Beans.
Sweet corn.
Sunflower.
Pumpkin.
Vegetable.
Different hole counts.
Different cell shapes.
Different thicknesses.
The boy found 24-B.
His finger landed on the line.
Plate 24-B — Medium Flat Corn — Series 6 / Series 8 / TwinDrop Units.
He looked toward his father.
His father looked at the plate.
Neither spoke.
Then the boy searched another number from memory.
18-R.
There.
Then 16-S.
There.
Another.
There.
His father sat slowly at the table.
“How many different numbers did you see?”
“Maybe fifty.”
His father exhaled.
“That doesn't mean they're valuable.”
“I know.”
“But they're real.”
“Yes.”
His father looked toward the stack of manuals.
Then toward his son.
“You may still have bought three hundred dollars of obsolete parts.”
The boy nodded.
“But now we know what obsolete parts.”
That was the first victory.
The next morning before chores, he began inventory.
One crate at a time.
He did not grind the rust.
The gray-haired farmer's warning stayed with him.
Instead he brushed gently with a stiff nylon brush.
Wiped dirt.
Read raised casting numbers.
His mother gave him index cards.
He wrote:
24-B — 11
24-C — 8
18-R — 17
32-A — 4
16-S — 21
M7 — 6
He stopped.
M7.
The gray-haired farmer.
If you find any marked M-7 sweet corn, call me.
