Great to hear that you like it Geoff. Thanks for a great transaction.
When I got the camera myself something like four years ago (from a ex-sailor who took it all over the planet for taking pictures during his short stays on land in various countries, he originally bought the camera while visiting Finland), the battery was pretty low and I figured it would die soon altogether. But it's still working the shutter many (~20-30) films later, so apparently it doesn't draw all that much power. Those mercury bateries are pretty tough anyway. I hope it will last you a long time longer. Bit fussy to go into alternatives.
Have fun with the camera and do its history some good credit. (Not saying that you should start sailing the world, but a small outing now and then might please it.)
