I was a Mont Blanc dealer for the corporate markets trade . Although my favorite has always been Parker I liked the features of the safety and used a few. Gradually I dropped all my Mont Blanc and concentrated on just vintage and modern Parker and Waterman pens. Here is a Mont Blanc #10 safety but it had a #8 nib. It was a massive pen, I believe it was about 6 inches long.
