Harry Lewington and Blake Scicluna starred with bat and ball as Farrer finally added one of the missing pieces to its trophy cabinet.
Before Tuesday the Tamworth school had never won the Davidson Shield.
They've been close, reaching the final on several occasions but falling short.
Early on in the final at Parkes, things were looking a bit shaky, but then Lewington and Scicluna took control.
After scoring 77 and 41, respectively, to steer Farrer to 169, the pair led the charge as they routed Corowa for just 36.
In the immediate aftermath coach Dave Olrich described the win as "very satisfying" and "very emotional", with the players dedicating the win to long-time Farrer coach John Kilborn.
The man affectionately known as Killer coached the First XI from 1976 through to 2013 and was in charge the last time they made the final, which was in 2009.
"We made a real point of putting everything into it for Killer, for everything he's done for Farrer," Olrich said.
"He's been to the final so many times but never won."
At least three by Kilborn's count.
"I was so pleased to hear they finally won one," he said.
Olrich was keeping him up to date of their progress during the day although didn't quite give him the full picture of their innings.
The text he got was they had made 169. Not that they were 4-41.
"It was very tough early," Olrich said.
"Their opening bowlers were great, one was unplayable."
But Lewington and Scicluna dug in and showed the patience that was required "until they could score freely".
They were then "outstanding" with the ball with Scicluna claiming 3-6 and Lewington 2-13 as Farrer wrapped up the historic win inside 18 overs.
Olrich also noted two "exceptional" run outs from deep in the field from Zac Craig and Adam Williams.
The region was well-represented in the finals, which were meant to be played in Bathurst the previous week but were washed out, with Inverell High's girls playing Corowa for the Marie Cornish Trophy.
They unfortunately went down.
