The SAC New Era may have been named the Model 401 based on the picture of the orphaned barrels below.

The serial number on the barrel flats would date this gun to the 1898-99 time frame and note that they are grade stamped “O1”; don’t know what that means, although “O” stamped guns designated twist steel barrels and I’m assuming the “1” stamp indicated line engraving? At any rate I have an Grade O1 gun in the 18XXX serial number range with twist barrels and line engraving; but it is marked Syracuse Arms.

The other pic is a New Era marked gun that actually has Syracuse Arms name and address atop the barrel.

I don’t have the serial number of the second gun but both of these guns feature pre-1902 First Model frames and features.
The cosmetic differences between the New Era gun and a standard Grade O Twist barreled SAC gun are a capped pistol grip (a special order feature on the standard Grade O SAC gun), checkered cheek panels, and a line engraved frame.

I have a Simmons Ad featuring a “NEW ERA” SAC gun exactly as depicted in The Fair NEW ERA ad
