Craig et al,
Commercial model, not military, SN C13761, which puts it in the latter part of 1914, the third year of production, the last patent date is 1913. All original high polish Colt blue finish with wear in spots, all matching numbers, original diamond checkered grips and a mirror bore.
Came from a 90 yr old ex dealer's collection. It supposedly belonged to a former WWI Army Colonel who purchased it after he mustered out because they wouldn't let him keep his military 45 and he wanted one. However the previous owner doesn't remember the Colonels name so any provenance is doubtful. However, I didn't "buy the story", just the gun. The wear on it is consistant with being carried some in a holster and being held and shot, but it was very well maintained, which an Army officer would be in the habit of doing.
I have found a period Heiser holster on ebay that is on its way to me, should make a great combo. Haven't had a chance to shoot it yet, hopefully later this week.
Jerry, I've been checking those out on ebay, I'll probably try to pick one up for it.
