Your welcome Steve! The truth is true!!
Cliffy do your wallet a favor and just get a zinc air battery and a #9 O-ring to go around it and that's the same as the Wein cell battery!! IF you don't use the camera for weeks at a time then to make the zinc air last longer you can place a piece of tape over the air holes to seal them up while not in use. Check out the link to the old topic steve provided and then make up your mind? Perhaps there is a camera shop you could have do the conversion for you? Or Someone maybe? It's up to you!
Cheers
