Default Re: Help ID a BSR Lid??

The molder would have been in big trouble if he modified the pattern. Patterns were expensive, and removing the ridge from one would mean it could never make a mold for a regular lid again. Modifying a sand mold so that a lid would be made without the ridge would require filling in a groove the entire circumference of the mold half. I would look at your lid closely for indication that someone perhaps just ground the ridge off the lid (for whatever reason).
