Gus had it right.
The true movie prop Quigley rifle(s) were made by Shiloh.
Go to:

Left menu on Rifle Models, then 1874, go down to the next to last picture for the REAL Quigley... complete with the owner's initials in gold, just like MQ on the movie guns.
Delivery time is long and price is high, but quality is great and it is of the closest possible authenticity from the original maker.
You/she could check with Bill Goodman; he keeps many orders in the works with Shiloh and I understand that up until they actually start work on a given gun, he can fudge the order to your specification... for $200 over list price, but delivery in 3 or 4 months.

C. Sharps makes rifles of equal quality, they both used to be part of the same company but went their separate ways a number of years ago.

They keep some rifles in stock and periodically update the list:

They say D21 is the Quigley configuration, but it is not quite the same as Shiloh's original. Price is no better, but immediate delivery.
All that said, the Pedersoli is not a bad gun. It is the only Italian copy I have seen at a high level of BPCR competition. It is less expensive, but the slide of the dollar versus the Euro has cut into the price advantage. E. Arthur Brown is not the only source. Check Dixie Gun Works has the Pedersoli Quigley for $1750 in .45-70, .45-90, or .45-120; but not the movie .45-110 for some reason. Probably because they could not get ammo in Italy to proof test the guns with, as required by Italian law.

Note that while the Shiloh Quigley includes the vernier tang rear and globe front sights, as does the C Sharps D21, most other makes and models do not. Those things are not cheap; the $150 Pedersoli sight is about the bottom of the line.
As Gus says, the movie authentic .45-110 is more demanding to shoot than the more common .45-70. Recoil is heavier. If he is not a proficient reloader, ammunition will be MUCH more expensive. If he is a reloader, and will load black powder, he can manage. The .45-110 will be harder to load satisfactorily with smokeless than .45-70.
As to "closest authenticity", the Quigley style rifle with military patchbox buttstock (left over from 1859 percussion models) and 34" barrel was built up to look impressive when carried by a tall movie actor. It is not what I would prefer for shooting. The narrow buttplate amplifies recoil, the loooong barrel is awkward and subject to "fouling out".
I think a No 1 Sporter with shotgun butt and 30" barrel would be easier to shoot. That is much more often seen at BPCR matches. (Well, except for MY position on the firing line, I shoot a Winchester, now a Browning copy of Winchester.)
