That is definitely a scarce gun. The serial number would be very helpful in determining just how scarce it is. It looks like a Lyman bead front sight, which while not rare, is probably original to the gun. The gun is before about 1916, because it still has the patent-date roll markings on the side of the barrel. They were moved back to the top of the barrel sometime around 1916. 124XXX is about 1910, so the barrel is probably correct.
The gun looks to have more than zero finish. It may not be much, but it may clean up to be reasonably presentable. Or, there may be a lot of cold blue that will wash off during a cleaning.
While I'd want to see the gun, I'd be a buyer if it were offered to me !
