I went back and checked my hooks. The lower hook is definitely a TMC 100, although I bought it years ago.
Here is a comparison image of a TMC 100 I grabbed off the web at Murray's Fly Shop's hooks. Click on "Murray's" and the photo is at the bottom lower right hand side of the page. It looks like the same hook shape to me.
Here is a Kamasan B17o "sproat" hook from Trout Catchers. The bend looks like the TMC 100 to me.
