Rathbun Bushing Used Inappropriately in Time & Strike Repair

I've been down the clock road a couple times but I've never seen this type of repair.  

A long time ago a repairperson used a Rathbun bushing to repair the depthing of the pallet arbor on an escapement.  This is not a proper repair.  I've seen this type of repair for clock wheels but not to adjust the depthing on a clock escapement.  Every time I see this repair I remove the Rathbun bushing and make it right, not this time.  The customer just wanted the clock to run and did not want a permeant repair.  My only recourse was to make the adjustment and tighten the screw.  As with all Rathbun bushings, this is only a temporary fix and not industry standard.  I post this only to demonstrate a unique and interesting application.  I do not condone this type of repair.

Here is a close up picture of the Rathbun bushing securing the pallet arbor.  The arrow shows the bushing:

When the clock was brought into the shop, the escapement was fluttering as seen in the video below.  Click the image below to see the fluttering.

From all indications, the screw holding the pallet arbor in place became loose and caused the misalignment.
