[Help with EB-4L]

The pickup ring was extended a bit on the one side I would think it’s for a thumb rest . Unfortunately it is no longer on the bass it was removed by the person that had it before me  .I got it from guitar center It was returned with a regular ring and no bridge cover .I got the pics from the web sight before I bought it  .  I guess the person bought the bass for the parts he needed then returned it .
