Your gun known as the "Flues Model" after its designer was made in 1918. These firearms were made in many different grades, which can have a huge affect on value. The condition of the firearm will, obviously, also have major impact on value. Assuming your gun is in good working condition and a FIELD grade gun, by far the most common, a 100% gun (as it came from the factory) could probably fetch close to $1500. A very poor example, still working though, about $300.
It is only worth what the person buys it for...

I am not sure about the age or value, but I would sure like to own it to rabbit hunt with.
It sounds to me like you have a Early made Ithaca Baker model double barrel shotgun made in 1889-1890.As to value I would have someone with the knowledge to evaluate you gun and then he could assign a value for you.
