Hi, my name is*****'m a certified appraiser and I'd be happy to help.
I'd need to see an overall photo, and a clear close-up of the marks you mention.
Photo upload instructions are here:
My apologies. I was away for the holiday.
Based on your photos, I don't feel I am the best person to appraise this. I opted out and opened this to other appraisers back on December 27, so it is open for any other appraiser to pick up if they feel qualified. This is a very specialized item.
