Big brown Santa Claus truck just dropped off my new London model with target sights. Obviously haven't had a chance to shoot it yet, but everything looks/feels pretty good so far. More pics/shooting report later, if anyone is interested.
Interested. More interested in mfr., dealer, date code, price, etc. By the V-shape of the loading aperture on the barrel lug it looks like an Uberti, not a Pietta.
Edit: Just looked at the Long Hunter website. If you paid that much for it, it had better work flawlessly.

Dovetail blade in front, square notch in the hammer. Perhaps not what modern shooters would call "target" sights, but if you ordered them on an original Colt, this is essentially what you would have gotten.
Expat_Alaska, Now that’s an interesting arrangement and something I consider as target sights. Wonder if the hammer spur is cut down in order for a clear view thru the rear sight.
I would not think the hammer spur would interfere, but maybe the hammer nose somewhat. I think the top of the rib is taller than the hammer nose, and the rear rib sight is taller than that.
It must also have been a special run of frames as the vertical ears on the recoils shields on either side of the hammer (to secure the barrel rib at the rear) are part of the frame. In 20/20 hindsight, my non-intuitional brain neglected to save the thread. I believe that they were made by Armi San Marco, but don't quote me on that.
I am done with this subject as I do not want to hijack the OP's thread. Apologies to .38 Special.

Jim
No worries. Any interesting conversation takes some side roads. For what it is worth I just arrived home and took a moment to look at the arbor. It appears that a hole was drilled in the end of it and a mushroom-shaped steel stud placed into it. I will need to find my magnifier to know for sure, but it is either welded, brazed, or epoxied into place. I hate to say it but I'm thinking JB Weld at the moment. Regardless, not as classy as I'd hoped, but at least the length is exactly right. Pictures when I have time and light.
Mr.38 special....does the gun come with the chambers opened up to be .001- .003 over groove diameter? I know they do that work on some of their guns
38,
I understand about the "thought" of JB but, I've used it for over 6 yrs and it's a pretty stable adhesive. Since I use a single spacer in the arbor hole to correct the arbor length, I'm switching to a "lock ring" which will expand into a groove to keep the spacer in place. A nice/neat mechanical way to remove the "epoxy" from the service.

Thanks for the reply!
There are a few ways it can be accomplished. I collect Italian replica revolvers and prefer to keep them as close factory originals as possible. I use .002" shim washers in a stack as a free assembly in the arbor recess to take up the slack and leave the arbor alone in case of resale, or in case I want to install a different barrel. I am a Pietta 1851 Navy parts changer and have 8 different versions (mostly Confederate) using 4 basic guns. This method works well if one keeps the stack with the assigned barrel and wedge.
With your gun, it has very many modifications so as not to resemble a factory gun. That is not a cut, sir. There is another thing to consider, which is the wedge contact at the rear of the arbor slot. If the wedge is too wide when driven in, it may push the barrel off of the frame pins, resulting in a larger barrel/cylinder gap than needed. .002" or less is preferable. Some folks install a small set screw in line with the arbor to limit the wedge travel into the wedge slot, and then install the remedy you described on top of that.
Very much looking forward to pictures.

* The only way this happens is when the wedge slot in the arbor is not cut far enough to the rear. The slot (in the arbor) must extend past the wedge slot in the barrel. Installed, the forward side of the wedge is bearing against the forward surface of the slot in the arbor, the rear of the wedge bears against the slot in the barrel ( the two sides of which make up the two rear points of a "triangulation" of which the front point is where the wedge contacts the arbor). That is how the wedge keeps the barrel assy installed on the arbor. Otherwise, if the wedge is contacting the rear of the slot in the arbor as well, there can't be any tension applied to the barrel assy nor will the barrel/cylinder change. (I run into this occasionally on old revolvers).
Some folks install a small set screw in line with the arbor to limit the wedge travel into the wedge slot, and then install the remedy you described on top of that.
* Maybe, but some of us install a rather large screw (1/4" ) which has proven to have plenty of bearing surface to allow use as an adjustable bearing. The normal bearing surface in this design/setup is a small "patch" of contact (as in the original revolvers). Contrary to some folks thoughts, the wider the contact patch (some think it should be full contact), the easier it is for the wedge to "walk" loose. The greatest amount of contact is where the rear of the wedge contacts each side of the barrel.
Until next time,
Mike
