Kevin,
Thanks for posting that list. That should give some folks a bit of pause when considering which replica 1851 is correct.

However, I am going to add to the confusion and use Swayze's book as affirmation:
I am going to copy and paste what I found about original Colt 1851 revolvers, originally written by Nathan Swayze.
7. There are two sizes of cylinder pins.
True, but the 1st Model had the wedge over the wedge screw, whereas the cylinder pin had a notch as opposed to a slot. Another variation. (pg 29, Plate 2).
9. There are two types of back straps.
There are four types of backstraps, two brass and two iron (pgs 134-135, Plate 82).
10. There are four shapes of trigger guards.
There are five differently shaped trigger guards (one squareback brass, 4 various round/oval configurations, some being either brass or iron ) (pgs. 135-137, Plate 83).
14. Ormsby's signature appears on some of the cylinders and not on others.
I have read that the die used to roll-stamp the cylinders wore out to the point that Ormsby's sig (being shallow) did not imprint. I have no cite on hand.
(Back to my thoughts)
In the originals, that makes up a great challenge to collect one specimen of each. I have handled a lot of originals and never paid any attention to the variations unless they were obvious or pointed out to me.
Modern replica's with variations are a wonderful chance to have a modest investment in a good collection.

You are one of the people I always rely upon for my info.
Thanks again, Kevin.
