Hi, Welcome to the Forum. I think a clearer image of the mark may be required. Try taking the photo on a plain piece of white paper, in this way the macro feature will focus on the mark rather the the background. Trev. hi thank you, is this picture any better? http://img841.imageshack.us/img841/720...
Got this from the US from an estate sale. It has a 925 mark on the boltring but also has this rhombus shape with a line going through the middle and was just wondering what it means and if its any hint to origin or date. Thank you.
