1900
Made in 1952
In order to determine the age of Lefever shotgun, the serial number must be known. However, Lefever shotguns were only made and distributed between 1885-1916.
I would say that with the serial number 1321XX,we are looking at your shotgun being made by ithaca(who made the lefever nitro special) in 1924.
If you are referring to an old double barrel, it was made in 1919.
1963
I have the exact same gun. I'm not sure exactly how old it is but it was my great grandfathers so it's probably 80+ years. These Guns were made until 1942 and ceased after the war was in full swing. newtest3 I have nearly the same shotgun as well, from all info I have gathered, it is a true Lefever design, which means it is pre-1921 and assembled by Ithica using left over parts from their buyout of Lefever Syracuse, NY. After '21, all info I have found point to Ithica selling a less than wonderful Ithica designed shotgun under the Lefever name. Ithaca bought out Lefever in 1916. In 1927 they intorduced the Lefever Single Barrel Long Range field and Trap model. Serial No. 11697 was mfg. in 1928 and the model was produced until 1942.
1927
