I'm rather curious if anyone has used an horological "topping tool"
(also known as a "rounding up tool") to recondition music box governor
gears, rather than replacing them.

 [  "The tool was made to 'top' or round the watch teeth that
 [  frequently were cut by a slitting saw, and so were flat bottomed
 [  and flat topped, so the topping tool rounded the tips of the gear
 [  teeth to enable correct meshing to occur.  Before the days of
 [  standardised machine tooling and cycloidal gear cutters, watch
 [  wheels had to be individually fitted using this tool."
