There are many things I have learned, and continue to learn about these rare Brevex actions. For example; like many others, I thought there were only 2 models, the M300 and the M400. Then some years later, I was contacted and shown pictures of two (2) M500 models, so now there are 3. We all learn as more information comes available.
