How do I know it was made in 1910? Well, here's a clue. The action was finished on June 15th, 1910 and signed by the technician!

Here's the action before reconditioning:

First, the action is disassembled until all that's left on the action frame...

are the Whippens and the Dampers:

Here's another view of the Dampers (at the top of the picture) and the Whippens (at the bottom). Notice that the damper springs have been moved aside and the felt that is normally in the spring seats have been removed before cleaning:

After the action and it's parts were cleaned in my glass bead blasting booth, new felt was glued into the spring seats:

In this picture you can see the Jacks of the Whippens having new graphite lubricant applied:

Here's the cleaned action frame. Notice that the old damper felts have been removed:

All of the action parts were individually cleaned. Here's a picture of the Damper lifter rod being cleaned:
