My first guess would be that it needs a real good cleaning, this is a gas operated and not a recoil action. They haven't made them in about 50 years there might be a bit of junk in there ;) Remember this is also Remington's first gas operated shotgun it and there have been a lot of improvements it won't be as forgiving as modern versions.
Yes I suppose it can.I would start my search for this part at numrich gun parts corp.They can be found on the web.But you will probably need to know who made your westernfield shotgun.The name westernfield was the store name brand for montgomery wards.
