They happen to be my favorite type of rifle too. Although myself, I do not care for the Webely, My tastes run towards Gibbs, Henry, H&H and Westley. I agree with Joe, get Wal's great book on them. Working drawings(blueprint type) do not exist as far as I know. If you are planning on trying to build one, you would be best off reverse engineering one from an original. I have a large action Webely I am currently restoring for a client currently but do not have the time to draw it up for you. Best of luck on your project.
