My wifes Father passed away last December and my son found and old US Arms OO Double 12 in the attic which I've come to understand is a "Trade Gun" made by Crescent Firearms.

Barrels are stamped "GENUINE ARMORY STEEL" and "CHOKED BORE" which seems to be another clue pointing to Crescent Firearms.

Based on serial numbers found on another web site for Crescent, the shotgun might be a 1900 model if the information on serial number below is reliable. The US Arms has all matching serial numbers, even the trigger side plates match!

1897 – 001 to 18,500
1898 – 18,501 to 37,000
1899 – 37,001 to 55,500
1900 – 55,501 to 74,000
1901 – 74,001 to 92,500
1902 – 92,501 to 111,000
1903 – 111,001 to 129,500
1904 – 129,501 to 148,000
1905 – 148,001 to 166,500
1906 – 166,501 to 185,000
1907 – 185,001 to 203,500
1908 – 203,501 to 222,000
1909 – 222,001 to 240,500
1910 – 240,501 to 259,000
1911 – 259,001 to 277,500
1912 – 277,501 to 296,000
1913 – 296,001 to 314,500
1914 – 314,501 to 333,000
1915 – 333,001 to 351,500
1916 – 351,501 to 370,000
1917 – 370,001 to 388,500
1918 – 388,501 to 390,350
1919 – 390,351 to 408,850
1920 – 408,851 to 427,350
1921 – 427,351 to 445,850
1922 – 445,851 to 464,350
1923 – 464,351 to 482,850
1924 – 482,851 to 501,350
1925 – 501,351 to 519,850
1926 – 519,851 to 538,350
1927 – 538,351 to 556,850
1928 – 556,851 to 573,350
1929 – 573,351 to 593,850
1930 – 593,851 to 612,350
1931 – 612,351 to 630,000

Found some parts on Numrich at: https://www.gunpartscorp.com/Manufacturers/Crescent-33192.htm

But cannot seem to find any Hammers, need both right and left.

Did find what looks to be an older William Moore & Company shotgun which has provided one hammer and springs needed to get the hammer mechanism in working order.

Used three of the trigger springs off the salvage gun, was a good thing because one of the original springs snapped when attempting to put the trigger mechanism back together last night. The salvage gun did provide a fair trigger guard, but the trigger spring was broken.

Would be happy to exchange parts from the salvage W Moore & Co shotgun, but would prefer to purchase parts. The Serial numbers do not match on the W Moore gun and it could be older than the US Arms OO.

Would like to replace the firing pins and the screws which hold them in place? And BTW are they supposed to have springs to hold the pins back? Need both right and left firing pins and screws.

Will be needing a stock and forearm when I get closer to getting it all back together. The forearm on the US Arms OO is in good condition and work great, glad that key piece of hardware is working correctly! The spring loaded lock latch is working perfect!

Found a few stock sites - would like feedback from anyone that may have purchased a stock from any of the following, only received feedback from one site thus far:

https://www.macongunstocks.com (Very nice, but very expensive!)
http://www.shop.macongunstocks.com/ (Better price)
http://www.gunstocksinc.com/ (Responded, but told me to look at web site)

Opinions - should I spend the money and get a nice stock or just go with plain since the US Arms OO is a "Trade or Hardware Gun".

The W Moore & Co salvage gun has a stock but is in very poor condition, almost like it was stored in a wet location!

Thanks to Dave for getting my access registered for this site. Hopefully someone can provide some much needed guidance!

From reading about Crescent Firearms they sold working guns and have no collectors.

Would at least like to make a nice wall hanger out of the shotgun and pass along to my son for his future family. Mostly as keepsake to remember their Grandfather.

Better yet it's a very tight gun just missing a few key parts! If it all fits together good and the gunsmith says OK, might reload a light load and give it a test fire!

Thanks in advance for any insight or assistance anyone may have for this project. This is my first attempt at such an old shotgun.

Cheers,

Steve
