When the Viking horn sounds for the first time at the packed ANZ Stadium on Sunday, there's a Gundagai electrician who can take credit for making it happen.
The three-metre fibreglass horn is Wayne Pollack's creation, knocked up in his shed at home with the help of a few mates.
After leading the Raiders team bus and Sydney-bound procession out of Canberra on the back of a flat-tray truck, the horn is now being set up in readiness for its customary role of signalling a "call to arms" for fans prior to the now-famous Viking clap.
And one thing is for certain: despite the impressive volume which resounded around Canberra Stadium before the preliminary final last Friday, the sheer crowd capacity generated by an NRL grand final will make Sunday's call the biggest yet.
The construction of the horn came after Raiders coach Ricky Stuart and the club's executive team visited the US in late 2015 to see how some of the top US football teams - gridiron or American football, as it's known here - manage their high performance programs and connect with their fans and communities.
The Minnesota Vikings, which play home games at Minneapolis's new US Bank stadium, the stage for last year's Super Bowl, also use a horn at their games but in a reverse way to Canberra's technique: they begin with a Viking clap and finish with the horn blast just before kick-off.
It's an impressive pre-game ritual and of thunderous proportions within Minnesota's 67,000-seat US$1 billion indoor stadium so it's little wonder the Raiders could see how the Green Machine's supporters would get behind the idea.
Once the horn concept was given the green light, it had to happen in a hurry before the 2017 season began.
Ben Pollack, the Raiders media manager, knew just the right person: his Dad.
A phone call to home and his father, Wayne, after thinking about it for a bit, took on the construction task as a challenge.
Providing a helping hand were some Gundagai locals Pete Smith, who makes moulds for concrete garden sculptures so knew how to work fibreglass, and spray painter Mark Smith.
"I'm handy at building things so we did some sketches and it went from there," Mr Pollack said.
"We shaped it using polystyrene foam, starting off with small round cross-sections and then increasing the sections in size.
"Once we had the shape and proportions right, we then fibreglassed it together."
Photos of the finished product were sent off to the Raiders for feedback, and were shown to the office staff for comment.
"They liked the horn but hated the colour," Mr Pollack said.
"And I guess they were right; it did look a lot like a over-ripe banana."
With time running out, the horn was then despatched to a specialist spray painter in Wagga Wagga, who colour-matched it with a real bull's horn.
The finished product was delivered to the Raiders on March 11, just within the the six-week timeframe.
For the mouthpiece, Wayne adapted the top of a pepper mill grinder.
The colour now even has its own name: Raiders horn.
A few seasons on and the Viking horn has now become a fixture at the Raiders' home games, with its amplified blast a Raiders run-on signature and a huge hit with the fans.
For the Raiders' team run-on this Sunday, the honour of sounding the horn to lead off what should be a Viking clap to remember, will rightfully go to one of the Raiders' most revered players, Mal Meninga.
It has been 25 years since Meninga led the green machine to grand final victory.
Watching on with pride from the grandstand will be Wayne Pollack.
