Hi AD. The short answer is, it's not that simple. Every lock, barrel, trigger, butt plate, trigger guard, and so on are different. And the type of rifle, and area it might have been made (referred to as "school") means each of those things will vary. So a blueprint, which I think is what you're looking for, doesn't exist. You need a blueprint like drawing so you understand how things fit, and that's fine. You also need a couple of the books mentioned above to show you how the lock you have will fit on the barrel you have, and how it needs to be set in the wood you have, and how the wood you have with that barrel and lock you have, need to fit to you so you can put in the trigger you have, on so on, and so on and so on.... These things fit together to fit you. You'll need some idea of what you want your rifle to look like (school), too. With this in mind, go back and cull some of the info above. A little spent on a book now will save a lot in headache medication later. And a new piece of wood or barrel.
