The good thing about the Brilliant is that it was made before 6x6 format was supported on the reverse of the backing paper, so it had to have it's own method of counting frames. This means that once you've got to frame one, you can set the internal frame counter and cover up the rear window with a bit of tape (or whatever) to prevent any light leaks. That's how I shot with it.The mirror's a but dusty but that won't affect your photos, of course, and you wont notice it anyway as you're shooting at waist level.I've put in some new seals where needed. Any questions, just message me.
