That sounds like an old French steel Solida cottered crank, so the BB cups "S" is probably Solida also. Is it steel with the arms held on with cotter pins? If so, this crank was pretty heavy and not rare or valuable, so it would probably be better to replace the crank and BB. With a French crank, one is always afraid the BB cups are French threaded, but if it is a Coventry Eagle frame, it is almost certainly English BB thread, which is essentially the same as modern ISO, so finding a new BB to fit the frame should not be a problem. Personally, on an English mixte frame, I'd use a TA or Stronglight crank, but a Campy crank and BB will be easy to find if you are willing to pay the price. As to crankarm length, 175 is noticeably different from 170. Also, unless your wife is quite tall, 175 is probably too long for her. Most average sized American women would ride 165 cranks, rarely more than 170.
