A couple more comparisons. The hinge pin on the Colt is screwed in and locked by a screw. The hinge pin on the Cimarron is just simple pin driven in. The top latch on the Colt is .4" longer than the Cimarron. The top tang is longer on the Cimarron.
The Colt has a plunger in the front lump that lifts when barrels open and hits against the locking bolt haunting the barrel opening. The Cimarron does not have this plunger.
This picture shows some of the nice figure in wood on the Cimarron. Not what you'd expect on an ugly duckling.
