Well I definitely differ to BSA, Winpoor, and reelman on determining what exactly this is. I do however have some experience in breaking down an action and selling it as parts. I have been known to do that a time or two in order to fund the purchase of long looked for and finally found pre-64 model 70. I would say if you break down that rifle you should get between 600-800 for that action alone if sold off in parts. The barrel if it is national match correct should be north of 150 easy, if not then 100$ assuming good bore and external bluing. The stock I have truly no idea since I have really never seen one sold on the open market, but I dont think I would take any less then 300 as I understand it they are rare and super hard to find. I think you should be able to clear at least 1000 on the low end and most likely much more if you broke it down to parts.
