Gruen Apprentice

Here's one that I've had for a long time sitting in the drawer with a broken staff. After a little research I got it running using the entire balance from a 329 movement, bridge and all. The 329 balance bridge and balance seems to be identical with the 520 movement. I suspect a lot of other parts are common between these movements.
