What's it for?

[ITSA426]

Cleaning out some of my junk I ran into a Chrysler starter with the number 1899200 on the lower case.  Solenoid on top.  I think it came out of the trunk of my four speed hemi car when I brought the car home.  I'ts been around here for several years.  My hemi has a lightweight starter in it now snd NAPA doesn't list a different starter for the hemi.  Anyone know for sure what it came from? 

Sorry no pics.  I'm trying to learn one thing at a time. 

Thanks, Lee
