As far as upper/lower case and hyphens - I'll pass.
As noted by member dddd, the shift lever mechanism can "gum up" . Also, some of the early down tube shift levers suffer from brittle failure of the indexing tabs. However, I believe that the stem sifters are similar to the thumb shifters, in that they are semi-sealed units, unlike the down tube shift levers.
Regarding the history and model name syntax, you'll just have to live with the ongoing discussion, as you're one who opened those cans.
