Hi Danit thanks for writing in with the following hallmark question:
"I found a ring at the second hand store, I don't know how old it is. On the inside there is a mark of 9 and the letter A with an arrow. Can you tell me what it means?"
Danit, Im not sure, how the arrow looks, is it going through the letter A?
An arrow going through an A in a circle was used by Arrow Manufacturing Co. The arrow goes through the top triangle in the A letter.
