True that^, the Passage was not a model listed in my Sutherlands, but it's supposedly 30.2mm stack ht. and like other Tange HS quite a bargain. Problem will be if you need French threading, I don't think Tange makes the Passage in FR, but you might get away with swapping all the lower stack and the upper race of the Passage and re-using your FR top cup and lock nut...maybe...it occasionally works out.
