Can anyone help me to identify and date this item. I have already learned by reading through the forum that one part of the mark is the jungin mark but can anyone tell me anything about the other mark and what it says.
The mark "純銀" means pure silver, and the mark “服部製” means "made by Hattori", so the marker and retailer is K. HATTORI & CO., Tokyo, Japan (current Seiko Holdings).
