The Chime coils are available locally - Check the sponsor's pages  You should stick with the original part numbers for the chimes as substituting them will make them sound different.

White for the top pair, red for the lower pair. There will be differences, but this would have been "factory". I have factory wafers in my Mata Hari.

Great pick up - Mata Hari is a classic !
