Hi. I have never seen these or know what to even call them.

Hey there,

The coil assembly you have bears a pretty close resemblance to the Series 140 Quick-Tilt Assembly. Since the housing is stamped with an 8, you can use the S104-08.

Be sure to carefully review and compare the dimensions to confirm that this the right right fit.
