"To find something significant, and different, is rare," said Victor Rolando, a member of the Manchester Historical Society who has been on-site throughout the demolition.
Rolando explained that they found a lot of old-style cut nails, as well as wooden pegs that would have held together joints in the old building.
"The items are not unique to this marble mill," he said. "They are common to construction in the late 1800s."
They also discovered hand-hewn beams.
"The beams could have come from anywhere," Rolando said. "They get recycled from different places... so they could have come here."
In carrying on the practice of recycling beams, Craig Hunter, Director of Facilities at Manchester Design Outlets, said that they have been sorting through the remains of the Sirloin Saloon building to find what they can recycle.
"We separated the metals... clean wood, and old beams," he said. "The metals will get recycled... we're going to hold onto [the beams] and possibly send them out to be recycled."
He said that they will not be using any of the old materials in the construction of the new building.
They did find some larger items, such as individual pieces to a drive train, drive shafts, and piping hoops that would have gone to a turbine.
"I'm disappointed that we didn't find a turbine," Rolando said.
Rolando explained that it isn't too out of the ordinary that they didn't find any large, valuable items; the mill would have sold off anything of value when they sold the building, in order to make more money.
The property saw a line of different mills before being turned into the Sirloin Saloon in the 1960s; it was originally a marble mill, then a wood mill, and finally a grain or grist mill.
Now that Rolando has finished his time on-site identifying and setting aside all historic items, he explained that it is up to Hunter to decide what to do with them. He said that perhaps he and Ben Hauben, the owner of Manchester Designer Outlets, would put them on display in the new plaza.
"When everything is done and we see what we have... we'll decide if they're worth displaying," said Hauben.
Hunter said that the site is nearly cleared of all materials
