Turn signal switch needed for 1955 Savoy

[CHS]

Try looking on ebay. I have seen them listed occasionally

I would like to find an original turn indicator switch for my Savoy. This is the sealed unit that fits inside the steering wheel hub. Does anyone have one they've parted out? Not sure if earlier and/or later years woiuld interchange, but they might. Thanks for any help.
