I have acquired a small collection of Sailor pens, and I'm looking for some information on the history of Sailor pens in order to identify them. I know that a lot of their pre-40's information was lost during the war, but I'm amazed at how little information I can turn up about their models from the 60's to the present. I've been able to find historic catalog pages and blogs about Pilot and Platinum, but I'm struggling with Sailor (apart from the 1911 model).
Does anyone have any catalogues of vintage Sailor pens (particularly from the 60's, 70's or 80's)? Or suggestions for a blog/website with more info?
