Lloyd,
Most times, for a beginning, the bushing assortments offered by the material suppliers are a good deal. If I am not mistaken, there should be an assortment for American clocks. This will likely cover all of the bushing sizes needed except for the winding arbors. No need to buy a bushing machine to install bushings, either. Many repair people will ream bushing holes with a hand tool and set the bushing with a small hammer. If you do not have a mentor to teach you how to install bushings, you probably will have to resort to the books. Check out your local library for clock repair books. If you want to know which books give the best explanations, let me know and I will do some research.
My compliments to you for the good photos provided.
Your movement will need a considerable amount of repair to make it dependable, but it is not an impossible task. Don't be overwhelmed and take it one step at a time.
To release the wheel that is peened, you may have to do some fancy filing with a needle file to release it. To reattach it you will probably have to peen it. The individual trundles (wires) should be able to be replaced in the escape wheel pinion. No need to replace the whole thing. One of the "books" should give a pretty good explanation of how to replace these. Hard wire should be available from the materials suppliers. Once the clock plates are separated, you should be able to wiggle the escape wheel free. If not, you may have to slightly bend the front bridge to get it out.
Always remember that the upper wheels in a movement are the ones getting the least amount of power and are most susceptible to wear.
Best of luck,
Dick
