About the only thing that most people do is change the shape of the cock. It is an excellent, very fast lock as is but the curve at the forward curve of the cock is maybe a little bigger than needs to be. There is quite a bit of material there that can be removed, making the lock a little more graceful and elegant than from the mold. It is even called the "Siler hump" among some builders it is so pronounced. When you get it, compare it with pictures of originals, you will see what needs to be done.
