Second Generation Colt's are getting scarcer and scarcer to find. Especially the presentation and limited edition models - it's next to impossible. So, I've decided to take my collecting in another direction; First Generation Colt's percussion revolvers - specifically 1851 Navies and 6 shot 1849 Pocket Models. My first foray into this is winning the bid on a Rock Island Auction lot that had one of each. Took delivery today on an early 3rd Model 1851 Navy made in 1852, and a 6 shot 1849 Pocket model made in 1863. Both are in what I would consider great shape for their age with some traces of original finish and fully functional with good lockup. All markings and cylinder scenes are present and legible. I may have paid too much; but I don't care.

Very nice. You going to shoot them? I have a couple 1849s and a navy and some others but no 6 shot '49s. I haven't shot any of mine yet.
 
Congratulations! Those look very nice. Looks like the edges are sharp, nice markings and good cylinder scene. I just got my first original too, a Remington 1863 New Model Army. The craftsmanship of these 19th Century guns is amazing.

Do you notice any significant difference in the balance of an original 1851 vs. a 2nd Gen 1851?
 
I spent an hour or so yesterday afternoon stripping the Navy down for a good inspection. All of the screws and nipples came out with little effort. I even used my zero torque $5 electric screwdriver getting them out. The nipples are unlike any I've seen before. The flash hole is too small for my nipple pick, the bottom is domed, and the sides are straight up & down, not tapered, and they are like new. The mainspring is about twice as thick as a Uberti or Pietta, which explains the extremely heavy cocking force required. It's sporting a standard Uberti spring now.. Cylinder cleaned up nicely, and the bore was worn & pitted as would be expected, but isn't really that bad. I didn't take any pictures during the process, It is sitting in the in safe ready to go out & make smoke. Plan is to do so this coming Saturday.

Tis pistol is in fine shape. Who ever had this before me took very, vey good care of it. It may have cost me a petty penny; but I think it was worth it. I just hope I have he same opinion after it gets used.
 
On your Navy, and since you are working on it, what are bore, approximate groove, and cylinder chamber mouth diameters, if you don't mind?

Very, very cool to have such historical pieces and to still be able to use them after all this time!
 
Here are a few more pictures of the Navy. The pocket model is in the shop getting the loading lever repaired.

Those look nice, Honest to God who cares the price as long as you are happy... Life is to short not to get something you long for...

Maybe the guns were meant to be sold to Australia, thats why the photos are upside down??? :)

I've compared the Navy to a 2nd Gen C series Navy and a stainless steel Uberti Navy.

Weight: 1st Gen - 2lb, 9 7/8 oz ; 2nd Gen - 2lb, 9 3/4 oz; Stainless Uberti - 2lb, 10 3/4 oz
Cylinder bore: 1st Gen - 0.374 to 0.375; 2nd Gen - 0.372 to 0.374; stainless Uberti - 0.371 to 0.373
Barrel: 1st Gen - 0.374 (?) ; 2nd Gen - 0.372 (?) ; Stainless Uberti - 0.371 (?)

Thank you for the response. I don't get close enough to originals to take them apart.

One question on second picture, middle barrel. Is that C Series? I've owned 5, all had rifling depth equivalent to stainless barrel on right. Middle barrel has relatively shallow rifling.

My goal is to understand whether "modern", shallow (< .004") rifling is losing something in accuracy and function.
By my measure:
original was .010" to .012" deep;
Uberti/2nd Gen is .008" to .010", up to 2010;
Pietta, & Uberti after 2010, .003" to .005".

Modern dogma has it that bullet should at least match groove diameter, & shallow rifling is all that is needed. Works for jacketed & alloy lead bullets. With C&B revolvers, recent manufacturers have the rifling shallow to better match chamber-mouth to groove diameter (result of consumer demand?) For CAS, shallow rifling is good enough (close range, opportunity to wipe barrel after every 5 shots.) Is shallow rifling best for soft pure lead bullets and black powder? Gain-twist rifling isn't missed anymore; what about depth?

Were the original Colt engineers using antiquated concepts for rifling depth, or did they know something modern makers choose to ignore?
