The elusive M5, bought, as "shutter not working" for £5...new battery+seals, cleaned inside and out, inc. lens. Works perfectly... As new...
Congratulations. You did better with your M5 than I (mine, shown earlier in this thread, was not repairable).
For anyone interested, there are two M5's for sale on the auction site now, one may be working.
