I have been looking through my blocks and some early ones.
1. Casting date 12/5/12 think number is 202+++. Screw in core plugs, looks like some older crack repair . I will pressure test it and see.
2. 11/??/16 looks ok, don’t see anything wrong, will pressure test.
Any interest. Can bring to Hershey, but not unless someone wants them.
Plan to look for more. Have a few more non starter blocks .
