Okay, now we've got a second mention of the 40.5 push-on filters. We're getting really curious what you find when back from your hols, Richard...

Epsilon shutters: hmm, well, we have one on a post-war 5in Ross WA. The lens is very sharp, but the shutter is a little unreliable indeed. We check it a couple of times before taking the plunge of making an exposure. What we really need to do is take it apart and take a long and severe look at its insides to make it behave properly. No idea why its so unstable. Bad design?
