It appears to be a six-shot .32 caliber top break of a style similar to a Smith & Wesson Double Action small frame revolver of the late 19th and early 20th century, but these were all five-shot models. Also, if the stocks are original they are definitely from another brand; someone here will probably be able to ID them.
In general guns of this type and era, even in exceptional condition, are in the $200-250 range at best. Hope this is helpful.
