Like Rebel Salute, Factory Warrior is owned by the Hick and Miller families from Camooweal.
They have owned the nine-time career winner since his earliest days as a race horse.
“He needed a fair bit of time off with his hoof issues and he eventually went on the auction site, before Wendy Hick bought him back,” the trainer said.
“I have looked after him with the hoof, it took us four or five months to get it right.
“It has taken a while to get his hoof right and it has been a rush to get his three country runs under his belt for this McKinlay race but we have done it now and he will be there on Saturday.”
Finter – who has a handful of gallopers in work on top of his full-time job in the mines – feels a solid 'miler' is needed to win the ORS Final.
As McKinaly has a lengthy sand straight, he believes the track races more like a mile distance than a 1500 metre surface.
Factory Warrior has improved with every run in the North West, finishing less than half a length behind the winner second-up before breaking through in the region over 1200 metres on Saturday in an Open Handicap.
“It is a great incentive, any race with extra prize money is,” Finter said of the ORS Final.
“A lot of people target it and this race was more or less his target since I got him.
“You have got to chase it when they are $20,000 to the winner.
“McKinlay is a good, big track and the straight is nearly 600 metres long, so it is more like a mile race with the long straight.”
ORS series heats were contested at Julia Creek, Barcaldine, Gregory Downs, Tambo and Longreach as well as two at Mount Isa.
The in-form Zoomaratta and the Toni Schofield-trained Cozhecancan are also expected to be contenders for the ORS Final this Saturday.
