If this item has value, consider getting it repaired/rewound.

Costly though.

Crammer will reply to most enquiries, eventually. In this instance though they will probably direct you to the manufacturer of the device if it was a bespoke design.

How did you determine the transformer being at fault?
You may post a photo of the device as well.

Probably the winding is broken at the pin, maybe it can be fixed if accessible
