I'm trying to date my Peterson Dublin Deluxe. I know that the third hallmark (left to right) represents the date. It looks like a wide "O" to me. I found this guide to English silver date marks http://www.silvercollection.it/englishsilverhallmarks.html It looks like 1949 to me but I don't see many that are that old. I may sell this pipe and don't want to misrepresent the age. If there's any Peterson buffs out there I would appreciate your input. Here is a link to the photo. Thanks!
