I realize this thread has departed from the original question that was posted but as usual threads seem to have a mind of their own as one question always leads to a dozen more.
I posted this information on the other Forum. I still have not been able to positively identify the Double Diamond or the Mofra markings. It has been discovered that there were numerous small “mom and pop” shops in the Brescia Italy. In the beginning of Uberti in around 1958, Navy Arms was their sole Distributor. Replica Arms started in around 1962-63. The big frame revolvers (Walkers, Dragoons, etc.) and the small frame revolvers (Baby Dragoons, Pocket Models, etc.) were manufactured by Armi San Marco. The Patersons appeared in the mid 1960’s with the markings of Mofra and the Double Diamond. The first Pietta marked Paterson in the RPRCA collection is 1969. It is new in the box made for Navy Arms with the only 7 ½” barrel observed by manufactured by Pietta. Most all Pietta’s have 9” barrels without loading lever. The only 7 ½” barrel Paterson with a loading lever was made by Uberti. Uberti started making the Paterson in 1988
RPRCA has fifteen Paterson revolvers in it’s collection with the earliest date of 1967. David’s Paterson is 1966 which helps date the advent of the production of the replica Paterson. It is interesting that the Mofra marking has only been observed on the barrels of Paterson revolvers. The Double Diamond started in around 1970 and the Mofra markings disappeared. This information is based on observations of the 950 revolvers in the RPRCA collection. The Double Diamond appears on other model replica revolvers into the late 1970’s. Other Double Diamond revolvers noted are the Spiller & Burr and the 1862 Pocket Navy.
I have been trying to put together the early relationship between Uberti and Armi San Marco. It seems that in the 1960’s there was definite “territories” for models produced to specific groups of manufacturers. Many small shops were used for component parts. Small shops who did not have the manufacturer’s license would market complete guns through the larger manufactures. This helped fill the orders from the U.S. for cheaper revolvers that the large producers did not want their name on. Even within the larger producers there was a definite range of quality that existed.
The complete history of these revolvers and the many manufacturers and distributors involved will probably never be known completely. This, of course, is what makes the replica revolvers of such great interest to the collector. It is the fun of discovery. For over 16yrs I have been collecting and researching these revolvers hoping to produce a book for potential collectors of replica revolvers and have yet to find a place to stop and publish. What I thought in the beginning would be a simple little “Collector’s Guide” is already over 600 pages and still expanding.
