Three original 1954 6v truck motors have sold on eBay in the last month (I have not seen a correct one on eBay before that).
I do not have to note that an original used motor would be 57 years old.
It seems that many of those used motors have a faulty/flakey switch on the motor body.
The modern after-market 1954/55 wiper motors (which are not reproduction wiper motors) will not work with the original radio/speaker in place. If this is important to you, check this with Newport Engineering. If they have a real 6v unit that works with the original radio, please let us know (or, maybe that is why they sell 6v to 12v inverters).
I had the 12v-wiper-for-6v-truck problem when buying an after-market 1954 wiper motor 10 years ago (they also told me it would work fine with an original radio/speaker - it did not).
