You have a well-made, but unexciting, firearm. Not really suitable for sporting purposes due to its age (possibly laminated barrels and probably short chambers) and not something sought by "serious" collectors (that means the ones who have money to burn). It really has value only as a mantle decoration. $75 if it is a single shot, up to $250 if it is a double with big side hammers.
CHeck the acution sites.
Since the company has been out of business for 97 years, you'll probably have to find a gunsmith who can custom make it or modify a forearm from a similar gun.
