AMI Welte-Mignon roll changer parts wanted

I am restoring a "Multi-Control" 10 roll changer for a Welte-Mignon Corp. Philharmonic reproducing pipe organ. It dates from sometime on or after 1925. Automatic Musical Instrument Company of Grand Rapids built these roll changers. Welte Philharmonic pipe organs were installed in the homes of the wealthy and with the Multi-Control you could program up to 10 rolls to play one after the other. A remote control box had 10 buttons where you could select the rolls you wanted to hear. The selector device itself is located in the roll changer. Pushing any of the buttons would also trip the line switch to start the vacuum pump.

The selector device is covered in patent 1,801,343 and can be seen here:

The selector device can be seen in sheet 7 of the drawings.

I suspect that the selector device was also used in early AMI jukeboxes.

I am missing one of the solenoid coils that lifts the selecting latches. Attached is a photo of the device. You can see the coils at the top of the device and the missing coil is 2nd from left. Might someone have any spare coils for this selector device?

I am also in need of a die cast pulley and yoke which served as a tensioning pulley for the drive belt that transmitted power from the vacuum pump shaft up to the operating shaft of the roll changer. Might early AMI jukeboxes have used drive belts with this tensioning pulley? Attached is a photo of this pulley and yoke. Might someone have one of these?

And finally, I have attached a photo of a complete roll changer which I think will be of interest to the members of this forum.

Thanks
