Sounds like a Dane rework. What it's worth, depends on a lot of things. Is the bore decent, pitted or worn is a major factor. The mix master of parts, is pretty normal. Are there any accessories, like sling, bayonet/scabbard, cleaning kit, ammo bandoleer etc? Has the stock been replaced with a Beech wood replacement?
If it has a Walnut stock, there isn't any rust or pitting inside or out and it has a decent bore, $750 to $1000. Condition is everthing, when it comes to milsurps. Without pictures it's impossible to give you a more exact price. It may even be worth less.
