I have a handful of old Cherry M* switches and took one apart. I couldn't tell the difference between mine and the ones already in the Wiki here: wiki/Cherry_gold_crosspoint but Daniel Beardsmore picked it off. He's been doing some good work on that page recently.
My examples have a solidly rectangular stationary contact where the the ones that are later that are currently depicted in the wiki are a little less substantial. Thought you guys might like to see these pics as they are going in the wiki.
