I may be wrong on this,but I don't think you can just locate barrels and a forend for that model gun, and expect everything to fit properly. It is my understanding that all doubles require custom fitting of barrels and forend to action. You may already be aware of this [if so disregard],but I would think that in some instances the job would not be too involved,but in others could be something quite expensive. Just a word of caution.
