I am looking for a second hand for a King Arthur T-520 grandfather clock made in Alabama. I believe it has an Urgos movement - UW-03038. I have tried a number of second hands, but this one seems to be unique. Seems that instead of just snapping on, this one has more of a tube stem, in order to engage with the drive. In addition, I'm looking for a clip that screws onto a rod in the mechanism that clicks into the different detents for the different chime options. Know of anything like that? Thanks for any info you can provide.
