Yes.
The Beretta Laramie and Taylors Frontier are the same revolver.
Uberti is the actual manufacturer. Uberti also makes replicas of the Schofield Model and the Russian Model. Again refer to my earlier photos to see what they look like.
As to your comment about the Laramie has the best quality of all the S&W Top Break replicas, as far as I can tell all three have the same quality.
Uberti is owned by Beretta, so the Laramie was marketed under the Beretta name, but it was actually made by Uberti.
The original New Model Number Three was cataloged from 1878 until 1908, although all frames had been manufactured before 1899, so as far as the BATF is concerned, they are all antiques.
Chambered for 17 different cartridges, 44 Russian was the most common.
Most of this model had cylinders that were 1 7/16" long. Not a problem with the standard 44 Russian cartridge, but 44-40 and 38-40 were too long to fit into that cylinder.
The New Model Number Three Frontier model had a cylinder 1 9/16" long and was chambered for 44-40. That is probably where Taylors got the idea to label theirs Frontier. Interestingly enough, Colt Single Action Army revolvers chambered for 44-40 were always referred to as the Frontier Six Shooter. Anyway, the 44-40 Frontier model was fairly scarce, only 2072 were made.
Even scarcer was the New Model Number Three 38 Winchester. This one also had a 1 9/16" long cylinder and was chambered for 38-40, also known as 38WCF (Winchester Center Fire). Quite rare, only 74 are known to have been made.
As with the other Uberti replicas of the S&W Top Breaks, Uberti lengthened the cylinder to accept longer cartridges such as 45 Colt. Uberti did this by shortening the collar at the front of the cylinder that shielded the cylinder arbor from powder fouling blasted out of the barrel cylinder gap. If you look carefully at the photo of the Laramie that you posted, compared to the photo of the New Model Number Three that I posted, you can see mine has a shorter cylinder and a longer gap between the front of the cylinder and the frame.
This photo shows the collar pressed into the front of the cylinder.
This photo shows the relationship of the collar or bushing on the front of the cylinder directly underneath the barrel. That is what Uberti shortened in order to make the cylinder long enough for 45 Colt or 44-40 without lengthening the frame. This design works very well when shooting cartridges loaded with Black Powder because the collar shields the underlying cylinder arbor from BP fouling blasted out of the cylinder gap. The Uberti version, not so much.
I consider myself lucky to own 2 New Model Number Three revolvers. The blue one shipped in 1896 to Taketa & Co. Yokohama, Japan. I found it at a gun show a few years ago and was all over it. I found a flaw in one of the chambers but the dealer said he doubted if anyone was going to shoot it. He did not know me very well. I have always wondered if it came back to the US in a GI's duffle bag at the end of WWII. The nickel plated one shipped in 1882 and was refinished at the factory in 1965. I have factory letters for both of them.
Parting Shot: Smith and Wesson never chambered any of their Top Break revolvers for 45 Colt.
