First one

When i picked this Keystone Watch Co. piece up a few years ago it wasn't running and the case was fully covered in rust...

The s.n. 354678. and is in a Keystone Case, found some original Keystone hands to contrast the white colored case...

Here is the movement... s.n. 354678.

Second one

Here is one of my favorites a Keystone Standard Watch Co. piece in a HC. gilded movement, Just need to find a new set of hands...

Here is a photo of the movement s.n. 145743.

Will just show you the Hunter Case...

And the markings inside the case, s.n. 2629338.

Rob, Very nice pieces. I would be seriously tempted to swap cases, as the Dustproof is far more valuable when correctly Hunter Cased . . . especially with those incredibly rare Keystone Hands.
