Friend found this at a gunshow a year or so ago. No italian proof marks and the only markins are EMF - SA under the ejector rod button, .38 special on the barrel and a serial number back to back on the lower front of the frame and the bottom rear of the barrel assembly. The finish is exceptional with dark blue case color that appears to be a real fire hardening process. The grips are fake ivory from a company Called "Buffalo"- also a gunshow find.
It hits right on top the sight picture with factory wadcutters, handles like a 61 navy. The action is smooth and the trigger pull light.

Shortly after he bought it, the extra thin mainspring broke and he replaced it with a generic part. The portion of the hammer that strikes the firing pin is kind of odd- a round stud screwed through the hammer. Beforehe locktited it, it would walk loose until firing pin contact became too light for postive ignition,

At first, we thought it was manufactured by Armi San Marco but the high quality of the action, the perfect alignment of the cylinder/barrel and the overall quality were not what ASM generally produced. It looks like it may be from the old Armi San Paolo plant now owned by EMF. Cimarron Arms has similiar ctg conversions/transitions from Uberti.
 
Being unmarked, I suspect Armi San Marcos manufacture. Many of those ASMs were sold as gunsmiths specials. Some were reworked, repolished and reblued and actually colour case hardened by gunsmiths. There was a problem with some criminal attempts to pass a few off as originals. Buffalo Brothers makes quite a selection of CAS kit. www.buffalobrothersstore.com

Looks like a copy of a Mason-Richards Conversion of an 1860 Army - probably with a '58 Navy grip frame. If it were an 1871/72 copy it would have a solid recoil shield - not two piece - and would have a loading gate identical to the 1873 SAA. Glad it shoots well - enjoy! :)
 
Sure does look like the pictures of the Richards in R.L. Wilson

Very likely this is an ASM finished in the US. Obviously somebody that cared about what he was doing ,got hold of it. Also some luck involved as ASM was pretty indifferent to chamber alignment and correct size of chambers and barrels.
 
I had the same revolver from Traditions-ASM. It passed the range rod alignment test with flying colours. Bore and chambers were off a little though. The chambers were at .358 and the bore was .361. I had to use hollow based lead bullets to obturate and fill the bore. It wasn't too accurate past 15 feet with factory 38 Specials. I have heard of even larger bores in some of those conversions. One thing that improves accuracy from them is cutting the forcing cone to 11 degrees and reaming the chambers true. I saw one that was bored off center and there isn't much that can be done with that.
 
sounds like a chamber ream and some hollow based healed bullets like the early cartridges might go good in that. We had an ASM Dragoon that wouldn't shoot until the owner used sandpaper to bring the chambers out to .454. After that, it did fine with .457 balls.
 
Yes, the bullets make all the difference. It has always struck me as odd that manufacturers or importers one don't establish proper specifications for chambers, bore size and alignment.
