bruce, our main focus at FineOldGuns.com (OldGuns.net) is military firearms. We sometimes list sporting shotguns for sale in our catalogs but we do not have a lot of interest in collecting them and are by no means experts in this field. There are several dealers listed on our links page that specialize in shotguns who would be able to give you a better answer to your question.

I tried a quick Google search on N. R. Davis And Sons which resulted with the following information at this link:

Short History of N.R. Davis & Sons Shotguns

This information written by and reprinted with the permission of Joe Vorisek
N.R. DAVIS ARMS COMPANY

This company. located in Assonet, MA from 1853 until at least 1917, operated under the following names:

1853 to 1883‑ N.R. DAVIS ARMS COMPANY‑ Freetown section of Assonet, MA

1883 to 1917‑ N.R. DAVIS & SONS CO.‑ Water St., Assonet, MA

1917 to 1930‑ DAVIS‑WARNER ARMS CORP.‑ Brooklyn, NY and Norwich, CT (There is some evidence that the Assonet factory remained in use until 1925.)

1930 to 1935‑ CRESCENT‑DAVIS ARMS CORP.

The company was owned and operated by the Davis family until 1917 when N.R. DAVIS & SONS CO. was merged with WARNER ARMS CORP. to form DAVIS‑WARNER ARMS CORP.

Davis‑Warner seems to have made both Davis shotguns and Warner pistols in small quantities with the guns being made at the Warner plant in Norwich, CT from parts made in the Assonet plant until about 1925.

Beginning in 1925, Davis‑Warner seems to have regained its ability to make and sell firearms in quantity. Perhaps because the Assonet plant was closed and production consolidated in Norwich. It also appears that the Warner automatic pistols were dropped from production in 1925.

When the Assonet plant actually closed is speculative, some sources use the 1917 date, while others use 1925; unfortunately the Assonet Town Records do not reflect the year of its closing. It was definitely closed and not in use when it burned in 1928 and newspaper articles about the fire indicate that it had been closed for some time.

DAVIS‑WARNER ARMS CORP. became a part of CRESCENT DAVIS ARMS CORP. in 1930. For further information regarding this merger see CRESCENT FIRE ARMS CO.

N.R. DAVIS shotguns were marked, in addition to the names above, with at least the following trade names.

E.C. MEACHAM ARMS CO. PAT'D AUG. 3, 1886
ASSONET GUN WORKS (probably) no specimens seen
RIVAL (hammerless double made in the 1880's)

N.R. DAVIS & SONS may also have made some shotguns for Sears, Roebuck, but this has not been confirmed by observation of any actual specimens.

Still another possibility has surfaced, namely that N.R. DAVIS may have made some shotguns that were totally unmarked except perhaps for a serial number for a few of the larger hardware wholesalers; but again this has not been confirmed by observation.

As may be apparent from this rambling discourse, very little hard evidence exists about N.R. DAVIS operations, despite its being a well known and well respected gun maker. One reason for this is that over much of its life it was family owned, and such firms rarely make much information public.

Even the question of how many shotguns it produced is a mystery. Some shotguns have serial numbers, while others have only a 2 digit assembly number; and there appears to be no rhyme or reason as to why some are serial numbered and some are not. Serial numbers of their lack will occur in the same models.

Much more specific research needs to be done on this company. I can only hope that this material will at least serve as a basis from which to start.

N.R. DAVIS & SONS made shotguns under at least the following patents:

66,913, July 16, 1867‑ breechloading firearm
81,348, August 25, 1868‑ method of attaching gun barrels
217,001, July 1, 1879‑ firearm
293,719, February 19, 1884‑ breechloading firearm
294,772, March 11, 1884‑ breechloading firearm
346,536, August 3, 1886‑ breechloading firearm

The principals of N.R. DAVIS & SONS CO. before 1917 were as follows:

Nathan Russel Davis
N.W. Davis (son of Nathan R.)
W.A. Davis (son of Nathan R.)
David C. Thresher (Thrasher)

The serial number ranges of Davis made shotguns may be impossible to recreate with any accuracy until some reason can be found for why some guns were serial numbered and some were not.

However one item does appear to be fact. That is that all Davis model shotguns made by DAVIS‑WARNER ARMS CORP. or CRESCENT‑DAVIS ARMS CORP. had a letter prefix to the serial number. Whether this prefix denotes the year of manufacture is open to conjecture.

One clue as to when a Davis‑Warner shotgun was made may be obtained from the very last guns produced in 1929 and 1930. These shotguns are marked on the water table, PAT. NO. 1,692,995. This patent was granted to a J.J. Murphy on November 27, 1928.

Hi Joel, I can usually clean up the firearms that are not Parkerized.  For Parkerized guns, the paint seems to get into the grain of the Parkerization and it is sometimes just about impossible to remove. Here is a list of chemicals that I have had some success with. Sometimes one of these will work on one gun but not another.  I usually try all of the chemicals on the list until I find one that works:

• WD-40
• Diesel Fuel
  
• Acetone
  
• Lacquer Thinner
  
• Mineral Spirits
  
• Paint Thinner
• Rubbing Alcohol
  

If the paint is old and hard sometimes you can soften it up by soaking.  I do this by putting a small bit of saturated cloth (like a cleaning patch) over the offending area and  let it soak in.  In the case of acetone, rubbing alcohol and lacquer thinner, they evaporate fast so you have to keep re-wetting the patch.  Once (if) the paint softens up, you can scrub with a stiff toothbrush, you may have to do this several times.  Sometimes with Parkerization, it leaves the area that was cleaned lighter because of white paint stains.  If that happens, the only thing that can be done is to rub in some old dirty grease or cosmoline, the blacker and dirtier the grease, the better.

I would caution you to experiment on small, a less noticeable area first before tackling an area that would stand out and be noticeable.
