Look at the cranes on most of the guns shown and compare them with the catalog pic, which is of a late example. The OP's gun is a type made from 1897-apparently, about early 1909, although I thought the change occurred about 1905. No US military use.
The gun is in awful shape and probably wears M-1917 military grips. Colt commercial grips, whether of hard rubber or wood, were generally checkered. Most NS revolvers have lanyard rings, regardless of commercial or police or Army use. Look at that gun in the 1931 catalog page photo.
I owned one made about 1935 that was in exceptionally nice condition, and it, unusual for a Colt, actually shot to the sights. At 25 yards, it was very accurate with commercial Remington 255 grain .45 Colt loads.
How did the OP's gun fare against that raccoon? Where was it hit and did it die promptly? What was the exact load used? How long was the range? How big was that coon? I think they can exceed 40 lbs.
Some use .22's on coons and others say they're pretty tough. I've seen them run in packs. They can carry rabies. I'd want to stop them with one shot, if at all possible. I do think the .45 Colt might be a good cartridge for that.
