i got a 12 gauge king nitro double barrel double triggers and double hammers no serial number on it
With the serial number that you provided,your Ithaca double barrel shotgun with the damascus barrels was produced in the year 1900.
I believe that King Nitro was a model name of Shapleigh Arms Co, St. Louis, MO.
$317
@ turn of the century; wall hanger to maybe 100 USD
The value of an old double barrel shotgun Damascus Bonehill Special BB London would actually be dependent upon a number of factors. Some of these factors would include the age exactly and the condition of the shotgun.
This should be a Lewis model, made in 1902.

1850-1870
No published sn data; 10-100 USD
The gun was produced c.1935 by Ithaca. Value will depend on condition, and can reach $500-$600.
Probably made somewhere between 1870 - 1910. If you were to tell everyone it was made around 1900 you wouldn't be far off either way.
