You learn something every day. Thanks for tthe information. I believe these are small denticles as the spacing is noticeable. I am not an expert but that would be my guess. I looked at it under a magnifying glass and compared it to the example. Hope this helps and hope I am not leading you wrong. Thanks again for the info.
